Eugene Koifman commented on HIVE-4773:
--------------------------------------
It's not clear why this solves the described problem. The code already called
writer.flush() which is now also followed by writer.close(). Why would flush()
not be sufficient?
Also,
'writer' is connected to System.err (or System.out). Is it really safe/OK to
close this stream? What about when this runs on Yarn which I believe does
some container reuse?

> With ASV as a default FS, we saw instances where output is not fully flushed
> to storage before the Templeton controller process exits. This results in
> stdout and stderr being empty even though the job completed successfully.
