Subject [jira] [Commented] (DRILL-6139) Travis CI hangs on TestVariableWidthWriter#testRestartRow
Date Thu, 08 Feb 2018 20:27:00 GMT

    [ https://issues.apache.org/jira/browse/DRILL-6139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16357522#comment-16357522
] 

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.
