commit # : 09b262776e965ea17a6a863801f7e1ee3e5b3d5a
Below is what I am describing:
1. One of the fragments cause a channel closed exception (due to an OOM or some other condition)
2. Drill fails all other fragments which are running at that time even though the fragments themselves eventually run to completion. At a high concurrency this could lead a lot of query failures.
