Review request for drill, Chris Westin and Jacques Nadeau.

Bugs: DRILL-2878

Repository: drill-git



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
