Subject [jira] [Commented] (HIVE-15541) Hive OOM when ATSHook enabled and ATS goes down
Date Tue, 24 Jan 2017 19:04:26 GMT

    [ https://issues.apache.org/jira/browse/HIVE-15541?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15836467#comment-15836467

Jason Dere commented on HIVE-15541:
-----------------------------------

Test were broken by HIVE-15297.
About fireAndForget() and conf, that variable is not final so it does not get used by the
Runnable. Will remove.

> The ATS API used by the Hive ATSHook is a blocking call, if ATS goes down this can block
the ATSHook executor, while the hook continues to submit work to the executor with each query.
> Over time the buildup of queued items can cause OOM.
