-Re: no _SUCCESS file in MR output directory.

I wanted to confirm whether oozie disables the _SUCCESS file creation when
it triggers a MR job.
I am triggering a MR job (actually a bunch of 'em) from oozie and the
workflow completes successfully , however I do not see any kind of _SUCCESS
file in the output directory.
When I set the file output committer's configuration
) to true.It generates the success file. Wanted to confirm if oozie does
the disabling of success file creation.
