>                 Key: HADOOP-1143
>                 URL: https://issues.apache.org/jira/browse/HADOOP-1143
>             Project: Hadoop
>          Issue Type: Bug
>          Components: dfs
>    Affects Versions: 0.10.0
>            Reporter: Konstantin Shvachko
>
> DFSOutputStream.handleSocketException() does not handle exceptions thrown inside it
> by abandonBlock(). I'd propose to retry abandonBlock() in case of timeout.
> In case of DFSOutputStream.close() the exception in handleSocketException() will result in
> calling abandonFileInProgress().
> In a similar case of DFSOutputStream.flush() the file will not be abandoned.
> Exceptions thrown by abandonFileInProgress() are not handled either.
> Feels like we need a general mechanism for handling all these things.
