I am seeing behaviour where I open a notebook and run a paragraph script in Zeppelin and the script executes and returns the result as expected. Then I leave the notebook open for a few hours - come back and attempt to re-run the same paragraph and get the error: "object 'hiveContext' not found". The only way to resolve this is by restarting the Spark interpreter. Is this expected behaviour? Is there a timeout on the hiveContext perhaps?
Any insight much appreciated

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

..also is there a way in SparkR to check first if the sparkcontext and hivecontexts are running?

@mike harding -> are you running Zeppelin (within HDP 2.5 Sandbox) or running Zeppelin standalone?

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.
