> 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

>                 continue;
>   }
> will just let set closed=true in closeInternal().

> It will leave the file in writing in incomplete state.
