---------------------------------------
Summary: 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: Tests
Reporter: Zoltan Haindrich
Assignee: Zoltan Haindrich
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....
