Dick King commented on MAPREDUCE-323:
-------------------------------------
I also fixed a problem with {{TestJobCleanup}} , which without this fix leaves
files in a temp directory, trashing a subsequent {{TestJobOutputCommitter}} run
if there is one before the temp directory is cleared. It's very annoying to
have tests that fail in a full unit test but not in isolation.
> Improve the way job history files are managed

> Today all the jobhistory files are dumped in one _job-history_ folder. This
> can cause problems when there is a need to search the history folder
> (job-recovery etc). It would be nice if we group all the jobs under a _user_
> folder. So all the jobs for user _amar_ will go in _history-folder/amar/_.
> Jobs can be categorized using various features like _jobid, date, jobname_
> etc but using _username_ will make the search much more efficient and also
> will not result into namespace explosion.
