@Yaron Idan You can also add spark client to a slave node and then add Zeppelin to that node.

Try enabling Spark debug and if possible get complete stack trace. Does the error only happen on Windows?

Livy sessions are recycled after an hour of session inactivity. This timeout is configured with livy.server.session.timeout

vshukla · ‎08-02-2016

Are you using Zeppelin directly with Spark interpreter or with Livy interpreter? In Z > Livy > Spark scenario, the Livy session is recycled some time of inactivity. I will report back if default timeout and how to configure it. To come out of this behavior, you will need to restart Livy interpreter.

Spark Streaming & Dynamic Resource Allocation is a new feature with Spark 2.0 (https://issues.apache.org/jira/browse/SPARK-12133) so it is not yet available in either HDP or CDH.

We still don't support Hive on Spark. We support Hive on Tez. We also support SparkSQL.
