Chris Westin created DRILL-2564:
-----------------------------------
Summary: TestWriteToDisk is flaky
Key: DRILL-2564
URL: https://issues.apache.org/jira/browse/DRILL-2564
Project: Apache Drill
Issue Type: Bug
Components: Storage - Other
Affects Versions: 0.8.0
Environment: OSX
Reporter: Chris Westin
Assignee: Jacques Nadeau
Roughly every third run of mvn install, TestWriteToDisk fails. I run it
standalone in an IDE, and it passes. I run mvn install again, and it passes.
Here's the stack trace I got from the most recent failure.

When this happens, I sometimes rm -rf /tmp/drill, and then it works again. But
I shouldn't have to do that, nor should this fail apparently at random.
