https://issues.apache.org/jira/browse/DRILL-2878
Repository: drill-git
Description
-------
*INITIAL-PATCH*
This is a "quick fix" that seem to solve the problem, at least for the cases I
am able to reproduce it for. closeOutResources() shouldn't throw any exception
at this point because we didn't even start running, and any allocation failures
will be suppressed (do we want this ?)
If this fix is acceptable I will go ahead and add a "private volatile boolean
startedRunning" that will be set to true in run() and used in cancel() to check
if we need to call closeOutResources().
I will also add a unit test, I know how to reproduce the problem for both the
root and intermediate fragments, but I still need to find a proper way to
detect that those fragments were not closed properly.
