--------------------------------------
Resolution: Not A Bug
> ChannelClosedException causes all queries which are communicating on that
> channel to fail
> ------------------------------------------------------------------------------------------
>
> Key: DRILL-4681
> 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.
