Timothy Farkas commented on DRILL-6139:
---------------------------------------
[~Paul.Rogers] Didn't know there was already a jira for this. I also created
https://issues.apache.org/jira/browse/DRILL-6144 for unit test hangs. But I
observed that the hangs were occurring in unit tests other than this one and
not just on Travis. After I increased direct memory to 5gb on jenkins and 4.6gb
on travis, the issue disappeared. I am going to open a PR with the increase in
memory. Perhaps if you find something during your investigation and have a fix
we can reduce the memory on our builds once the fix goes in.
Also as a side note, I noticed some unit tests where allocators are created and
never closed. I'm a bit hazy on the details but I believe MiniPlanUnitTestBase
is one of these offending test classes.
