Subject [jira] [Commented] (HIVE-4773) Templeton intermittently fail to commit output to file system
Date Tue, 24 Sep 2013 00:23:02 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13775848#comment-13775848
] 

Eugene Koifman commented on HIVE-4773:
--------------------------------------

[~shuainie] OK, I misread your code.  You only use CustomFilterOutputStream to wrap System.out/System.err
but not when 'out' = statusdir.  I get it now, so your changes do the same thing as I was
suggesting in previous comment.

I would suggest calling this wrapper class NonClosableStream, and making close() method in
it do nothing.  (also make class private).  I think this will make it easier to understand.

> 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.
