Then in order to make this work I recycle (stop/start) Zeppelin daemon and
things start working.
Is this behavior expected or is this due to excessive memory usage/GC issue.
FYI I am using zeppelin-0.6.1

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

with 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.

Hi Felix,
Yes it is the same host that I run Spark shell and I start Zeppelin on.
Have you observed this before?

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?

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
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
Dr Mich
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.
