> Metastore connection leaks in HiveServer2
> -----------------------------------------
>
> Key: HIVE-12790
> URL: https://issues.apache.org/jira/browse/HIVE-12790
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 1.1.0
> Reporter: Naveen Gangam
> Assignee: Naveen Gangam

> HiveServer2 keeps opening new connections to HMS each time it launches a
> task. These connections do not appear to be closed when the task completes
> thus causing a HMS connection leak. "lsof" for the HS2 process shows
> connections to port 9083.

> The TaskRunner thread starts a new SessionState each time, which creates a
> new connection to the HMS (via Hive.get(conf).getMSC()) that is never closed.
> Even SessionState.close(), currently not being called by the TaskRunner
> thread, does not close this connection.
> Attaching a anonymized log snippet where the number of HMS connections
> reaches north of 25000+ connections.
