Zoltan Haindrich updated HIVE-18383:
------------------------------------
Component/s: Metastore
> Qtests: running all cases from TestNegativeCliDriver results in OOMs
> --------------------------------------------------------------------
>
> Key: HIVE-18383
> URL: https://issues.apache.org/jira/browse/HIVE-18383
> Project: Hive
> Issue Type: Bug
> Components: Metastore, Tests
> Reporter: Zoltan Haindrich
> Assignee: Zoltan Haindrich
> Priority: Major
>
> I think that it is caused by unclosed SessionState objects which are piling
> up and cause OOM..
> There is special have been made to start a new sessionstate for every qtest;
> but the old one is not closed up to this
> [point|https://github.com/apache/hive/blob/20c9a3905f4b1b627c935ad54a53a7a59015587c/itests/util/src/main/java/org/apache/hadoop/hive/ql/QTestUtil.java#L1202]
> this prevents running all {{TestNegativeCliDriver}} tests in one maven
> call....I keep getting OOMs
> This issues sometimes appears on the ptest executor as well and its reported
> as a failed batch.
> I've gone back in time a bit....seems like at
> c925cf8d2bdf646f5c3c57ed7252c01b2ab33eec it was ok to execute the whole
> batch; but at 1b4baf474c15377cc9f0bacdda317feabeefacaf and probably also at
> a42314deb07a1c8d9d4daeaa799ad1c1ebb0c6c9 its not possible anymore. I suspect
> that there is possibly another issue....or these are just the consequences
> that the sessionstate got heavier by a few hundred bytes; and made it easier
> to fill up the heap....
