-----------------------------------
Summary: Increase tez.am.resource.memory.mb for TestIcebergCliDrver
Key: HIVE-27916
URL: https://issues.apache.org/jira/browse/HIVE-27916
Project: Hive
Issue Type: Bug
Components: Test
Affects Versions: 4.0.0-beta-1
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
Fix For: 4.0.0
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.
