Subject [jira] [Commented] (HIVE-10146) Not count session as idle if query is running
Date Tue, 07 Apr 2015 04:09:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482546#comment-14482546
] 

Lefty Leverenz commented on HIVE-10146:
---------------------------------------

Doc note:  This adds *hive.server2.idle.session.check.operation* to HiveConf.java, so it needs
to be documented in the HiveServer2 section of Configuration Properties for release 1.2.0.
 It could go either at the end of the section or after *hive.server2.idle.session.timeout*
(which could include a reference to it).

* [Configuration Properties -- HiveServer2 | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-HiveServer2]
* [Configuration Properties -- HiveServer2 -- hive.server2.idle.session.timeout | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.server2.idle.session.timeout]

> Currently, as long as there is no activity, we think the HS2 session is idle. This makes
it very hard to set HIVE_SERVER2_IDLE_SESSION_TIMEOUT. If we don't set it long enough, an
unattended query could be killed.
> We should provide an option to not to count the session as idle if some query is still
running.
