----------------------------------

What version are you seeing this issue in? I noticed something similar when producing HDFS-915
on trunk, but haven't seen it on 0.20.1

> processDatanodeError-> setupPipelineForAppendOrRecovery  will set streamerClosed to
be true if all nodes in the pipeline failed in the past, and just return.
> Back to run() in data streammer,  the logic 
>  if (streamerClosed || hasError || dataQueue.size() == 0 || !clientRunning) {
>                 continue;
>   }
> will just let set closed=true in closeInternal().
> And DataOutputStream will not get a chance to clean up. The DataOutputStream will throw
exception or return null for following write/close.
> It will leave the file in writing in incomplete state.
