+<h1>Spark Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="http://spark.apache.org";>Apache Spark</a> is a fast and
general-purpose cluster computing system.
+It provides high-level APIs in Java, Scala, Python and R, and an optimized
engine that supports general execution graphs.
+Apache Spark is supported in Zeppelin with Spark interpreter group which
consists of below five interpreters.</p>

+
+<p>Without any configuration, Spark interpreter works out of box in local
mode. But if you want to connect to your Spark cluster, you'll need to
follow below two simple steps.</p>
+
+<h3>1. Export SPARK_HOME</h3>
+
+<p>In <code>conf/zeppelin-env.sh</code>, export <code>SPARK_HOME</code>
environment variable with your Spark installation path.</p>
+
+<p>For example,</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span><span class="nb">export</span> <span
class="nv">SPARK_HOME</span><span class="o">=</span>/usr/lib/spark
+</code></pre></div>
+<p>You can optionally set more environment variables</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span><span class="c1"># set hadoop conf dir</span>
+<span class="nb">export</span> <span class="nv">HADOOP_CONF_DIR</span><span
class="o">=</span>/usr/lib/hadoop
+
+<span class="c1"># set options to pass spark-submit command</span>
+<span class="nb">export</span> <span
class="nv">SPARK_SUBMIT_OPTIONS</span><span class="o">=</span><span
class="s2">"--packages com.databricks:spark-csv_2.10:1.2.0"</span>
+
+<span class="c1"># extra classpath. e.g. set classpath for hive-site.xml</span>
+<span class="nb">export</span> <span
class="nv">ZEPPELIN_INTP_CLASSPATH_OVERRIDES</span><span
class="o">=</span>/etc/hive/conf
+</code></pre></div>
+<p>For Windows, ensure you have <code>winutils.exe</code> in
<code>%HADOOP_HOME%\bin</code>. Please see <a
href="https://wiki.apache.org/hadoop/WindowsProblems";>Problems running Hadoop
on Windows</a> for the details.</p>
+
+<h3>2. Set master in Interpreter menu</h3>
+
+<p>After start Zeppelin, go to <strong>Interpreter</strong> menu and edit
<strong>master</strong> property in your Spark interpreter setting. The value
may vary depending on your Spark cluster deployment type.</p>
+
+<p>For example,</p>
+
+<ul>
+<li><strong>local[*]</strong> in local mode</li>
+<li><strong>spark://master:7077</strong> in standalone cluster</li>
+<li><strong>yarn-client</strong> in Yarn client mode</li>
+<li><strong>yarn-cluster</strong> in Yarn cluster mode</li>
+<li><strong>mesos://host:5050</strong> in Mesos cluster</li>
+</ul>
+
+<p>That's it. Zeppelin will work with any version of Spark and any
deployment type without rebuilding Zeppelin in this way.
+For the further information about Spark & Zeppelin version compatibility,
please refer to "Available Interpreters" section in <a
href="https://zeppelin.apache.org/download.html";>Zeppelin download page</a>.</p>
+
+<blockquote>
+<p>Note that without exporting <code>SPARK_HOME</code>, it's running in
local mode with included version of Spark. The included version may vary
depending on the build profile.</p>
+</blockquote>
+
+<h3>3. Yarn mode</h3>
+
+<p>Zeppelin support both yarn client and yarn cluster mode (yarn cluster mode
is supported from 0.8.0). For yarn mode, you must specify
<code>SPARK_HOME</code> & <code>HADOOP_CONF_DIR</code>.
+You can either specify them in <code>zeppelin-env.sh</code>, or in interpreter
setting page. Specifying them in <code>zeppelin-env.sh</code> means you can use
only one version of <code>spark</code> & <code>hadoop</code>. Specifying
them
+in interpreter setting page means you can use multiple versions of
<code>spark</code> & <code>hadoop</code> in one zeppelin instance.</p>
+
+<h3>4. New Version of SparkInterpreter</h3>
+
+<p>There's one new version of SparkInterpreter with better spark support
and code completion starting from Zeppelin 0.8.0. We enable it by default, but
user can still use the old version of SparkInterpreter by setting
<code>zeppelin.spark.useNew</code> as <code>false</code> in its interpreter
setting.</p>
+
+<h2>SparkContext, SQLContext, SparkSession, ZeppelinContext</h2>
+
+<p>SparkContext, SQLContext and ZeppelinContext are automatically created and
exposed as variable names <code>sc</code>, <code>sqlContext</code> and
<code>z</code>, respectively, in Scala, Python and R environments.
+Staring from 0.6.1 SparkSession is available as variable <code>spark</code>
when you are using Spark 2.x.</p>
+
+<blockquote>
+<p>Note that Scala/Python/R environment shares the same SparkContext,
SQLContext and ZeppelinContext instance.</p>
+</blockquote>
+
+<p><a name="dependencyloading"> </a></p>
+
+<h3>How to pass property to SparkConf</h3>
+
+<p>There're 2 kinds of properties that would be passed to SparkConf</p>
+
+<ul>
+<li>Standard spark property (prefix with <code>spark.</code>). e.g.
<code>spark.executor.memory</code> will be passed to <code>SparkConf</code></li>
+<li>Non-standard spark property (prefix with <code>zeppelin.spark.</code>).
e.g. <code>zeppelin.spark.property_1</code>, <code>property_1</code> will be
passed to <code>SparkConf</code></li>
+</ul>
+
+<h2>Dependency Management</h2>
+
+<p>There are two ways to load external libraries in Spark interpreter. First
is using interpreter setting menu and second is loading Spark properties.</p>
+
+<h3>1. Setting Dependencies via Interpreter Setting</h3>
+
+<p>Please see <a
href="../usage/interpreter/dependency_management.html">Dependency
Management</a> for the details.</p>
+
+<h3>2. Loading Spark Properties</h3>
+
+<p>Once <code>SPARK_HOME</code> is set in <code>conf/zeppelin-env.sh</code>,
Zeppelin uses <code>spark-submit</code> as spark interpreter runner.
<code>spark-submit</code> supports two ways to load configurations.
+The first is command line options such as --master and Zeppelin can pass these
options to <code>spark-submit</code> by exporting
<code>SPARK_SUBMIT_OPTIONS</code> in <code>conf/zeppelin-env.sh</code>. Second
is reading configuration options from
<code>SPARK_HOME/conf/spark-defaults.conf</code>. Spark properties that user
can set to distribute libraries are:</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>spark-defaults.conf</th>
+ <th>SPARK_SUBMIT_OPTIONS</th>
+ <th>Description</th>
+ </tr>
+ <tr>
+ <td>spark.jars</td>
+ <td>--jars</td>
+ <td>Comma-separated list of local jars to include on the driver and
executor classpaths.</td>
+ </tr>
+ <tr>
+ <td>spark.jars.packages</td>
+ <td>--packages</td>
+ <td>Comma-separated list of maven coordinates of jars to include on the
driver and executor classpaths. Will search the local maven repo, then maven
central and any additional remote repositories given by --repositories. The
format for the coordinates should be
<code>groupId:artifactId:version</code>.</td>
+ </tr>
+ <tr>
+ <td>spark.files</td>
+ <td>--files</td>
+ <td>Comma-separated list of files to be placed in the working directory of
each executor.</td>
+ </tr>
+</table>
+
+<p>Here are few examples:</p>
+
+<ul>
+<li><code>SPARK_SUBMIT_OPTIONS</code> in <code>conf/zeppelin-env.sh</code></li>
+</ul>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span> <span class="nb">export</span> <span
class="nv">SPARK_SUBMIT_OPTIONS</span><span class="o">=</span><span
class="s2">"--packages com.databricks:spark-csv_2.10:1.2.0 --jars

/path/mylib1.py,/path/mylib2.zip,/path/mylib3.egg"</span>
+</code></pre></div>
+<ul>
+<li><code>SPARK_HOME/conf/spark-defaults.conf</code></li>
+</ul>
+<div class="highlight"><pre><code class="language-text"
data-lang="text"><span></span> spark.jars
/path/mylib1.jar,/path/mylib2.jar

+ spark.files /path/mylib1.py,/path/mylib2.egg,/path/mylib3.zip
+</code></pre></div>
+<h3>3. Dynamic Dependency Loading via %spark.dep interpreter</h3>
+
+<blockquote>
+<p>Note: <code>%spark.dep</code> interpreter loads libraries to
<code>%spark</code> and <code>%spark.pyspark</code> but not to
<code>%spark.sql</code> interpreter. So we recommend you to use the first
option instead.</p>
+</blockquote>
+
+<p>When your code requires external library, instead of doing
download/copy/restart Zeppelin, you can easily do following jobs using
<code>%spark.dep</code> interpreter.</p>
+
+<ul>
+<li>Load libraries recursively from maven repository</li>
+<li>Load libraries from local filesystem</li>
+<li>Add additional maven repository</li>
+<li>Automatically add libraries to SparkCluster (You can turn off)</li>
+</ul>
+
+<p>Dep interpreter leverages Scala environment. So you can write any Scala
code here.
+Note that <code>%spark.dep</code> interpreter should be used before
<code>%spark</code>, <code>%spark.pyspark</code>, <code>%spark.sql</code>.</p>
+
+<p>Here's usages.</p>

+<h2>ZeppelinContext</h2>
+
+<p>Zeppelin automatically injects <code>ZeppelinContext</code> as variable
<code>z</code> in your Scala/Python environment. <code>ZeppelinContext</code>
provides some additional functions and utilities.
+See <a
href="../usage/other_features/zeppelin_context.html">Zeppelin-Context</a> for
more details.</p>
+
+<h2>Matplotlib Integration (pyspark)</h2>
+
+<p>Both the <code>python</code> and <code>pyspark</code> interpreters have
built-in support for inline visualization using <code>matplotlib</code>,
+a popular plotting library for python. More details can be found in the <a
href="../interpreter/python.html">python interpreter documentation</a>,
+since matplotlib support is identical. More advanced interactive plotting can
be done with pyspark through
+utilizing Zeppelin's built-in <a
href="../usage/display_system/angular_backend.html">Angular Display System</a>,
as shown below:</p>
+
+<p><img class="img-responsive"
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/matplotlibAngularExample.gif"
/></p>
+
+<h2>Interpreter setting option</h2>
+
+<p>You can choose one of <code>shared</code>, <code>scoped</code> and
<code>isolated</code> options wheh you configure Spark interpreter.
+Spark interpreter creates separated Scala compiler per each notebook but share
a single SparkContext in <code>scoped</code> mode (experimental).
+It creates separated SparkContext per each notebook in <code>isolated</code>
mode.</p>
+
+<h2>IPython support</h2>
+
+<p>By default, zeppelin would use IPython in <code>pyspark</code> when IPython
is available, Otherwise it would fall back to the original PySpark
implementation.
+If you don't want to use IPython, then you can set
<code>zeppelin.pyspark.useIPython</code> as <code>false</code> in interpreter
setting. For the IPython features, you can refer doc
+<a href="python.html">Python Interpreter</a></p>
+
+<h2>Setting up Zeppelin with Kerberos</h2>
+
+<p>Logical setup with Zeppelin, Kerberos Key Distribution Center (KDC), and
Spark on YARN:</p>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/kdc_zeppelin.png"></p>
+
+<h3>Configuration Setup</h3>
+
+<ol>
+<li><p>On the server that Zeppelin is installed, install Kerberos client
modules and configuration, krb5.conf.
+This is to make the server communicate with KDC.</p></li>
+<li><p>Set <code>SPARK_HOME</code> in
<code>[ZEPPELIN_HOME]/conf/zeppelin-env.sh</code> to use spark-submit
+(Additionally, you might have to set <code>export
HADOOP_CONF_DIR=/etc/hadoop/conf</code>)</p></li>
+<li><p>Add the two properties below to Spark configuration
(<code>[SPARK_HOME]/conf/spark-defaults.conf</code>):</p>
+<div class="highlight"><pre><code class="language-text"
data-lang="text"><span></span>spark.yarn.principal
+spark.yarn.keytab
+</code></pre></div></li>
+</ol>
+
+<blockquote>
+<p><strong>NOTE:</strong> If you do not have permission to access for the
above spark-defaults.conf file, optionally, you can add the above lines to the
Spark Interpreter setting through the Interpreter tab in the Zeppelin UI.</p>
+</blockquote>
+
+<ol>
+<li>That's it. Play with Zeppelin!</li>

+<h1>Explore Apache Zeppelin UI</h1>
+
+<div id="toc"></div>
+
+<h2>Main home</h2>
+
+<p>The first time you connect to Zeppelin (<a
href="http://localhost:8080/";>default installations start on
http://localhost:8080</a>), you'll land at the main page similar to the
below screen capture.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/homepage.png" /></p>
+
+<p>On the left of the page are listed all existing notes. Those notes are
stored by default in the <code>$ZEPPELIN_HOME/notebook</code> folder.</p>
+
+<p>You can filter them by name using the input text form. You can also create
a new note, refresh the list of existing notes
+(in case you manually copy them into the <code>$ZEPPELIN_HOME/notebook</code>
folder) and import a note.</p>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/notes_management.png"
width="230px" /></p>
+
+<p>When clicking on <code>Import Note</code> link, a new dialog open. From
there you can import your note from local disk or from a remote location
+if you provide the URL.</p>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/note_import_dialog.png"
/></p>
+
+<p>By default, the name of the imported note is the same as the original note
but you can override it by providing a new name.</p>
+
+<p><br /></p>
+
+<h2>Menus</h2>
+
+<h3>Notebook</h3>
+
+<p>The <code>Notebook</code> menu proposes almost the same features as the
note management section in the home page. From the drop-down menu you can:</p>
+
+<ol>
+<li>Open a selected note</li>
+<li>Filter node by name</li>
+<li>Create a new note</li>
+</ol>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/notebook_menu.png"
width="170px" /></p>
+
+<h3>Settings</h3>
+
+<p>This menu gives you access to settings and displays information about
Zeppelin. User name is set to <code>anonymous</code> if you use default shiro
configuration. If you want to set up authentification, see <a
href="../setup/security/shiro_authentication.html">Shiro Authentication</a>.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/settings_menu.png"
width="170px" /></p>
+
+<h4>About Zeppelin</h4>
+
+<p>You can check Zeppelin version in this menu.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/about_menu.png"
width="450px" /></p>
+
+<h4>Interpreter</h4>
+
+<p>In this menu you can:</p>
+
+<ol>
+<li>Configure existing <strong>interpreter instance</strong></li>
+<li>Add/remove <strong>interpreter instances</strong></li>
+</ol>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/interpreter_menu.png" /></p>
+
+<h4>Credential</h4>
+
+<p>This menu allows you to save credentials for data sources which are passed
to interpreters.</p>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/credential_menu.png" /></p>
+
+<h4>Configuration</h4>
+
+<p>This menu displays all the Zeppelin configuration that are set in the
config file <code>$ZEPPELIN_HOME/conf/zeppelin-site.xml</code></p>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/configuration_menu.png"
/></p>
+
+<p><br /></p>
+
+<h2>Note Layout</h2>
+
+<p>Each Zeppelin note is composed of 1 .. N paragraphs. The note can be viewed
as a paragraph container.</p>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/note_paragraph_layout.png"
/></p>
+
+<h3>Paragraph</h3>
+
+<p>Each paragraph consists of 2 sections: <code>code section</code> where you
put your source code and <code>result section</code> where you can see the
result of the code execution.</p>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/paragraph_layout.png" /></p>
+
+<p>On the top-right corner of each paragraph there are some commands to:</p>
+
+<ul>
+<li>execute the paragraph code</li>
+<li>hide/show <code>code section</code></li>
+<li>hide/show <code>result section</code></li>
+<li>configure the paragraph</li>
+</ul>
+
+<p>To configure the paragraph, just click on the gear icon:</p>
+
+<p><img
src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/paragraph_configuration_dialog.png"
width="180px" /></p>
+
+<p>From this dialog, you can (in descending order):</p>
+
+<ul>
+<li>find the <strong>paragraph id</strong> (
<strong>20150924-163507_134879501</strong> )</li>
+<li>control paragraph width. Since Zeppelin is using the grid system of
<strong>Twitter Bootstrap</strong>, each paragraph width can be changed from 1
to 12</li>
+<li>move the paragraph 1 level up</li>
+<li>move the paragraph 1 level down</li>
+<li>create a new paragraph</li>
+<li>change paragraph title</li>
+<li>show/hide line number in the <code>code section</code></li>
+<li>disable the run button for this paragraph</li>
+<li>export the current paragraph as an <strong>iframe</strong> and open the
<strong>iframe</strong> in a new window</li>
+<li>clear the <code>result section</code></li>
+<li>delete the current paragraph</li>
+</ul>
+
+<h3>Note toolbar</h3>
+
+<p>At the top of the note, you can find a toolbar which exposes command
buttons as well as configuration, security and display options.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/note_toolbar.png"
/></p>
+
+<p>On the far right is displayed the note name, just click on it to reveal the
input form and update it.</p>
+
+<p>In the middle of the toolbar you can find the command buttons:</p>
+
+<ul>
+<li>execute all the paragraphs <strong>sequentially</strong>, in their display
order</li>
+<li>hide/show <code>code section</code> of all paragraphs</li>
+<li>hide/show <code>result section</code> of all paragraphs</li>
+<li>clear the <code>result section</code> of all paragraphs</li>
+<li>clone the current note</li>
+<li>export the current note to a JSON file. _Please note that the <code>code
section</code> and <code>result section</code> of all paragraphs will be
exported. If you have heavy data in the <code>result section</code> of some
paragraphs, it is recommended to clean them before exporting</li>
+<li>commit the current node content</li>
+<li>delete the note</li>
+<li>schedule the execution of <strong>all paragraph</strong> using a CRON
syntax</li>
+</ul>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/note_commands.png"
width="300px"/></p>
+
+<p>On the right of the note tool bar you can find configuration icons:</p>
+
+<ul>
+<li>display all the keyboard shorcuts</li>
+<li>configure the interpreters binding to the current note</li>
+<li>configure the note permissions</li>
+<li>switch the node display mode between <code>default</code>,
<code>simple</code> and <code>report</code></li>
