Summary: RemoteInterpreter Heartbeat
Key: ZEPPELIN-539
URL: https://issues.apache.org/jira/browse/ZEPPELIN-539
Project: Zeppelin
Issue Type: New Feature
Components: zeppelin-interpreter
Reporter: Jungtaek Lim
>From ZEPPELIN-535, I addressed that remote interpreter can become not able to
>respond for some circumstances, for example, OOME.
There're two scenarios, which one is that remote interpreter is not killed but
not respond, another one is that remote interpreter is killed.

Determining such scenarios requires analysis of Zeppelin's logs which seems not
easy thing to normal users, and users cannot do within Zeppelin UI.
Furthermore, in order to make it back to normal, users should restart
interpreter by hand.
It would be help to users when Zeppelin determines remote interpreter's status
and let users know when it's not able to respond.
It would be more better to restore remote interpreter if possible.
