I was under the impression that it was based on zeppelin or originally
started based on it.
it would be interesting to see how it was developed as it is a relatively
new comer.

Hi,
As I understood Cloudera Data Science Workbench was based on Zeppelin.
Zeppelin as open source was supported by Hortonworks and Cloudera took
Zeppelin and created the Workbench.
As anyone within Zeppelin community come across this Workbench and how do
you rate it?
Thanks

Hi,
Has anyone recently evaluated Zeppelin versus Jupyter versus H2O Flow by
any chance?
I have used Zeppelin and really a fan of it. However, I have not any
exposure to Jupyter or H2O Flow.
I was wondering anyone has pros and cons for each of these products by any
chance.
Thanks,
Dr Mich
you can use zeppelin scheduler to execute it every few seconds assuming
that zeppelin has sufficient to execute every instance of the code

also noticed recently that
Hortonworks are actively promoting Zeppelin. However, I do appreciate that
there are fans of Python around.
May be a strategy would to offer both. Having said that there are hard core
users that would never give up on Tableau!

Hi,
I think tempTable is private to the session that creates it. In Hive temp
tables created by "CREATE TEMPORARY TABLE" are all private to the session.
Spark is no different.
The alternative may be everyone creates tempTable from the same DF?

HDFS with in-memory storage where app 2
can pick up app1 results from memory or even SSD and do the work.
Actually I am surprised why Spark has not incorporated this type of memory
as temporary storage.

Thanks Chanh,
Can it share RDDs.
Personally I have not used either Alluxio or Ignite.
1. Are there major differences between these two
2. Have you tried Alluxio for sharing Spark RDDs and if so do you have
any experience you can kindly share
Regards

something like Apache Ignite.
Has anyone really tried this. Will that work with multiple applications?
It looks feasible as RDDs are immutable and so are registered tempTables
etc.
Thanks

What are you doing in Spark that causes Zeppelin to throw that error.
Have you loaded Jars to the interpreter as dependencies as well?

Is this behavior expected or is this due to excessive memory usage/GC issue.
