Stamatis Zampetakis updated HIVE-27695: --------------------------------------- Attachment: am_heap_dumps.tar.xz > Intermittent OOM when running TestMiniTezCliDriver > -------------------------------------------------- > > Key: HIVE-27695 > URL: https://issues.apache.org/jira/browse/HIVE-27695 > Project: Hive > Issue Type: Bug > Components: Test > Affects Versions: 4.0.0-beta-1 > Reporter: Stamatis Zampetakis > Assignee: Stamatis Zampetakis > Priority: Major > Attachments: am_heap_dumps.tar.xz > > > Running all the tests under TestMiniTezCliDriver very frequently (but still > intermittently) leads to OutOfMemory errors. > {noformat} > cd itests/qtest && mvn test -Dtest=TestMiniTezCliDriver > {noformat} > I set {{-XX:+HeapDumpOnOutOfMemoryError}} and the respective heapdumps are > attached to this ticket. > The OOM is thrown from the application master and a quick inspection of the > dumps shows that it comes mainly from the accumulation of Configuration > objects (~1MB each) by various classes. > The max heap size for application master is pretty low (~100MB) so it is > quite easy to reach. The heap size is explicitly very low for testing > purposes but maybe we should re-evaluate the current configurations for the > tests. -- This message was sent by Atlassian Jira (v8.20.10#820010)
