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
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.
