Andrei Stankevich created ZEPPELIN-2795:
-------------------------------------------
Summary: Close spark interpreter if it was not used for some
period of time
Key: ZEPPELIN-2795
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2795
Project: Zeppelin
Issue Type: Improvement
Reporter: Andrei Stankevich
When we use scope 'Per Note Isolated' Zeppelin creates spark context for each
notebook. If notebook was run only once or when we stopped using notebook that
notebook still have spark context related to it and it is holding cluster
resources.
With scope 'Per Note Isolated' after some period of time we have a lot of
spark contexts that are not used but they are holding cluster resources. These
contexts are related to notebooks that are note used any more.
It would be nice to have property that allows us to set some interval and if
spark contexts wasn't used more than that interval it should be closed
automatically by Zeppelin.
Same is true for Per User Isolated scope.
