-------------------------------------
Summary: Broken RemoteInterpreterService.Client is reused, not
discarded
Key: ZEPPELIN-534
URL: https://issues.apache.org/jira/browse/ZEPPELIN-534
Project: Zeppelin
Issue Type: Bug
Reporter: Jungtaek Lim
Priority: Minor
Looking into the Zeppelin code, there're getClient() and releaseClient() in
RemoteInterpreterProcess, but RemoteInterpreterProcess doesn't expose
releaseBrokenClient() which discards broken client from pool.
This means Zeppelin always return Client to pool whether it is broken or not,
so broken Client instances are reused or even leaked if releaseClient() is not
called.
