[jira] [Commented] (HIVE-9601) New Beeline queries will hang If Beeline terminates in-properly [Spark Branch]

["Szehon Ho (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-9601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14314489#comment-14314489 ] 

Szehon Ho commented on HIVE-9601:
---------------------------------

Some comments, this problem seems to be about orphan sessions leaving resources open, in this case the Remote Spark Application.  The orphan sessions take up resources as specified by 'spark.cores.max', 'spark.executor.memory', leaving no room for others.

The properties 'hive.server2.session.check.interval, hive.server2.idle.session.timeout' seem to help this case.  I couldn't find any other way to identify orphan sessions via Thrift and close them.

> User session's Spark application seems to stay around if beeline is not quit properly (!quit) because the user is not disconnected.
> If Beeline is started, it will create a new Spark application which will hang waiting for the first one.
