+<h1>Livy Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="http://livy.io/";>Livy</a> is an open source REST interface for
interacting with Spark from anywhere. It supports executing snippets of code or
programs in a Spark context that runs locally or in YARN.</p>
+
+<ul>
+<li>Interactive Scala, Python and R shells</li>
+<li>Batch submissions in Scala, Java, Python</li>
+<li>Multi users can share the same server (impersonation support)</li>
+<li>Can be used for submitting jobs from anywhere with REST</li>
+<li>Does not require any code change to your programs</li>
+</ul>
+
+<h3>Requirements</h3>
+
+<p>Additional requirements for the Livy interpreter are:</p>
+
+<ul>
+<li>Spark 1.3 or above.</li>
+<li>Livy server.</li>
+</ul>
+
+<h2>Configuration</h2>
+
+<p>We added some common configurations for spark, and you can set any
configuration you want.
+You can find all Spark configurations in <a
href="http://spark.apache.org/docs/latest/configuration.html#available-properties";>here</a>.
+And instead of starting property with <code>spark.</code> it should be
replaced with <code>livy.spark.</code>.
+Example: <code>spark.driver.memory</code> to
<code>livy.spark.driver.memory</code></p>
+

+<p><strong>We remove livy.spark.master in zeppelin-0.7. Because we sugguest
user to use livy 0.3 in zeppelin-0.7. And livy 0.3 don't allow to specify
livy.spark.master, it enfornce yarn-cluster mode.</strong></p>
+
+<h2>Adding External libraries</h2>
+
+<p>You can load dynamic library to livy interpreter by set
<code>livy.spark.jars.packages</code> property to comma-separated list of maven
coordinates of jars to include on the driver and executor classpaths. The
format for the coordinates should be groupId:artifactId:version.</p>
+
+<p>Example</p>

+<table class="table-configuration">
+ <tr>
+ <th>Property</th>
+ <th>Example</th>
+ <th>Description</th>
+ </tr>

+<h2>Impersonation</h2>
+
+<p>When Zeppelin server is running with authentication enabled,
+then this interpreter utilizes Livyâs user impersonation feature
+i.e. sends extra parameter for creating and running a session
("proxyUser": "${loggedInUser}").
+This is particularly useful when multi users are sharing a Notebook server.</p>
+
+<h2>Apply Zeppelin Dynamic Forms</h2>
+
+<p>You can leverage <a href="../usage/dynamic_form/intro.html">Zeppelin
Dynamic Form</a>. Form templates is only avalible for livy sql interpreter.</p>
+<div class="highlight"><pre><code class="sql language-sql"
data-lang="sql"><span class="o">%</span><span class="n">livy</span><span
class="p">.</span><span class="k">sql</span>
+<span class="k">select</span> <span class="o">*</span> <span
class="k">from</span> <span class="n">products</span> <span
class="k">where</span> <span class="err">${</span><span
class="n">product_id</span><span class="o">=</span><span
class="mi">1</span><span class="err">}</span>
+</code></pre></div>
+<p>And creating dynamic formst programmatically is not feasible in livy
interpreter, because ZeppelinContext is not available in livy interpreter.</p>
+
+<h2>Shared SparkContext</h2>
+
+<p>Starting from livy 0.5 which is supported by Zeppelin 0.8.0, SparkContext
is shared between scala, python, r and sql.
+That means you can query the table via <code>%livy.sql</code> when this table
is registered in <code>%livy.spark</code>, <code>%livy.pyspark</code>,
<code>$livy.sparkr</code>.</p>
+
+<h2>FAQ</h2>
+
+<p>Livy debugging: If you see any of these in error console</p>
+
+<blockquote>
+<p>Connect to livyhost:8998 [livyhost/127.0.0.1, livyhost/0:0:0:0:0:0:0:1]
failed: Connection refused</p>
+</blockquote>
+
+<p>Looks like the livy server is not up yet or the config is wrong</p>
+
+<blockquote>
+<p>Exception: Session not found, Livy server would have restarted, or lost
session.</p>
+</blockquote>
+
+<p>The session would have timed out, you may need to restart the
interpreter.</p>
+
+<blockquote>
+<p>Blacklisted configuration values in session config: spark.master</p>
+</blockquote>
+
+<p>Edit <code>conf/spark-blacklist.conf</code> file in livy server and comment
out <code>#spark.master</code> line.</p>
+
+<p>If you choose to work on livy in <code>apps/spark/java</code> directory in
<a href="https://github.com/cloudera/hue";>https://github.com/cloudera/hue</a>,
+copy <code>spark-user-configurable-options.template</code> to
<code>spark-user-configurable-options.conf</code> file in livy server and
comment out <code>#spark.master</code>.</p>

+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="https://pig.apache.org/";>Apache Pig</a> is a platform for
analyzing large data sets that consists of
+a high-level language for expressing data analysis programs,
+coupled with infrastructure for evaluating these programs.
+The salient property of Pig programs is that their structure is amenable to
substantial parallelization,
+which in turns enables them to handle very large data sets.</p>
+
+<h2>Supported interpreter type</h2>
+
+<ul>
+<li><p><code>%pig.script</code> (default Pig interpreter, so you can use
<code>%pig</code>)</p>
+
+<p><code>%pig.script</code> is like the Pig grunt shell. Anything you can run
in Pig grunt shell can be run in <code>%pig.script</code> interpreter, it is
used for running Pig script where you donât need to visualize the data, it is
suitable for data munging. </p></li>
+<li><p><code>%pig.query</code></p>
+
+<p><code>%pig.query</code> is a little different compared with
<code>%pig.script</code>. It is used for exploratory data analysis via Pig
latin where you can leverage Zeppelinâs visualization ability. There're 2
minor differences in the last statement between <code>%pig.script</code> and
<code>%pig.query</code></p>
+
+<ul>
+<li>No pig alias in the last statement in <code>%pig.query</code> (read the
examples below).</li>
+<li>The last statement must be in single line in <code>%pig.query</code></li>
+</ul></li>
+</ul>
+
+<h2>How to use</h2>
+
+<h3>How to setup Pig execution modes.</h3>
+
+<ul>
+<li><p>Local Mode</p>
+
+<p>Set <code>zeppelin.pig.execType</code> as <code>local</code>.</p></li>
+<li><p>MapReduce Mode</p>
+
+<p>Set <code>zeppelin.pig.execType</code> as <code>mapreduce</code>.
HADOOP_CONF_DIR needs to be specified in
<code>ZEPPELIN_HOME/conf/zeppelin-env.sh</code>.</p></li>

+<li><p>Tez Mode</p>
+
+<p>Only Tez 0.7 is supported. Set <code>zeppelin.pig.execType</code> as
<code>tez</code>. HADOOP_CONF_DIR and TEZ_CONF_DIR needs to be specified in
<code>ZEPPELIN_HOME/conf/zeppelin-env.sh</code>.</p></li>
+<li><p>Spark Local Mode</p>
+
+<p>Only Spark 1.6.x is supported, by default it is Spark 1.6.3. Set

+<li><p>Spark Mode</p>
+
+<p>Only Spark 1.6.x is supported, by default it is Spark 1.6.3. Set
<code>zeppelin.pig.execType</code> as <code>spark</code>. For now, only
yarn-client mode is supported. To enable it, you need to set property
<code>SPARK_MASTER</code> to yarn-client and set <code>SPARK_JAR</code> to the
spark assembly jar.</p></li>
+</ul>
+
+<h3>How to choose custom Spark Version</h3>
+
+<p>By default, Pig Interpreter would use Spark 1.6.3 built with scala 2.10, if
you want to use another spark version or scala version,
+you need to rebuild Zeppelin by specifying the custom Spark version via
-Dpig.spark.version=<custom_spark_version> and scala version via
-Dpig.scala.version=<scala_version> in the maven build command.</p>
+
+<h3>How to configure interpreter</h3>
+
+<p>At the Interpreters menu, you have to create a new Pig interpreter. Pig
interpreter has below properties by default.
+And you can set any Pig properties here which will be passed to Pig engine.
(like tez.queue.name & mapred.job.queue.name).
+Besides, we use paragraph title as job name if it exists, else use the last
line of Pig script.
+So you can use that to find app running in YARN RM UI.</p>

+<h3>Example</h3>
+
+<h5>pig</h5>
+<div class="highlight"><pre><code class="text language-text"
data-lang="text">%pig
+
+bankText = load 'bank.csv' using PigStorage(';');
+bank = foreach bankText generate $0 as age, $1 as job, $2 as marital, $3 as
education, $5 as balance;
+bank = filter bank by age != '"age"';
+bank = foreach bank generate (int)age,
REPLACE(job,'"','') as job, REPLACE(marital,
'"', '') as marital, (int)(REPLACE(balance,
'"', '')) as balance;
+store bank into 'clean_bank.csv' using PigStorage(';'); --
this statement is optional, it just show you that most of time %pig.script is
used for data munging before querying the data.
+</code></pre></div>
+<h5>pig.query</h5>
+
+<p>Get the number of each age where age is less than 30</p>
+<div class="highlight"><pre><code class="text language-text"
data-lang="text">%pig.query
+
+bank_data = filter bank by age < 30;
+b = group bank_data by age;
+foreach b generate group, COUNT($1);
+</code></pre></div>
+<p>The same as above, but use dynamic text form so that use can specify the
variable maxAge in textbox.
+(See screenshot below). Dynamic form is a very cool feature of Zeppelin, you
can refer this <a href="(../usage/dynamic_form/intro.html">link</a>) for
details.</p>
+<div class="highlight"><pre><code class="text language-text"
data-lang="text">%pig.query
+
+bank_data = filter bank by age < ${maxAge=40};
+b = group bank_data by age;
+foreach b generate group, COUNT($1) as count;
+</code></pre></div>
+<p>Get the number of each age for specific marital type,
+also use dynamic form here. User can choose the marital type in the dropdown
list (see screenshot below).</p>
+<div class="highlight"><pre><code class="text language-text"
data-lang="text">%pig.query
+
+bank_data = filter bank by
marital=='${marital=single,single|divorced|married}';
+b = group bank_data by age;
+foreach b generate group, COUNT($1) as count;
+</code></pre></div>
+<p>The above examples are in the Pig tutorial note in Zeppelin, you can check
that for details. Here's the screenshot.</p>

+
+<p>Data is shared between <code>%pig</code> and <code>%pig.query</code>, so
that you can do some common work in <code>%pig</code>,
+and do different kinds of query based on the data of <code>%pig</code>.
+Besides, we recommend you to specify alias explicitly so that the
visualization can display
+the column name correctly. In the above example 2 and 3 of
<code>%pig.query</code>, we name <code>COUNT($1)</code> as <code>count</code>.
+If you don't do this, then we will name it using position.
+E.g. in the above first example of <code>%pig.query</code>, we will use
<code>col_1</code> in chart to represent <code>COUNT($1)</code>.</p>
