Brock Noland commented on HIVE-5502:
------------------------------------
Gotcha. Thanks for taking a look.
bq. Since now you are testing using maven there might be some difference in
ANT_OPTS vs MAVEN_OPTS. Thats my guess.
bq. Implement a deterministic memory manager
OK these two together make sense as I was seeing the failures under maven with
the exact same M2_OPTS. I suppose it's possible that that some no M2_OPTS
cause non-determinism and my current ANT_OPTS do not.
bq. Overwrite golden file when we move to maven
I am not sure this will work since we cannot control. M2_OPTS on developers
machines.
