>                 URL: https://issues.apache.org/jira/browse/DRILL-4681
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Execution - Flow, Execution - RPC
>    Affects Versions: 1.7.0
>            Reporter: Rahul Challapalli

> 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.
