----------------------------------------
Resolution: Duplicate
> DFSOutputStream reference should be cleared from DFSClient#filesBeingWritten
> if the file closure fails.
> -------------------------------------------------------------------------------------------------------
>
> Key: HDFS-4855
> URL: https://issues.apache.org/jira/browse/HDFS-4855
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Affects Versions: 2.0.4-alpha
> Reporter: Vinay
> Assignee: Vinay
> Fix For: 2.0.4.1-alpha
>
>
> If the file closure fails due to some exception, then {{DFSOutputStream}}
> reference should be removed from the {{DFSClient#filesBeingWritten}}.
> Which is useless to keep and also memory consuming.
> If the same client is being used for long time,, then there is a chance of
> client getting OOM due to this.
> fix would be simple.
> Just cover complete {{DFSOutputStream#close()}} under try-finally and move
> {{dfsClient.endFileLease(src);}} to finally block.
> Any thoughts..?
