Thomas Rebele commented on HIVE-24680:
--------------------------------------
I've executed the test locally with {{{}mvn test -pl itests/qtest -Pitests
-Dtest=TestMiniLlapCliDriver -Dqfile=unionDistinct_1.q{}}}. It uses a bit more
than 6GB memory. That might make the OutOfMemoryError more likely.
> TestMiniLlapCliDriver unionDistinct_1.q is flaky
