Resolution: Fixed
I haven't seen this in forever, so probably fixed. Closing.
> Stale user directories left on TTs after MAPREDUCE-856

> Key: MAPREDUCE-1019
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1019
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: tasktracker
> Affects Versions: 0.21.0
> Reporter: Vinod Kumar Vavilapalli
>
> MAPREDUCE-856 changed the directory structure of job files on the TT. As part
> of this, it introduced user directories under taskTracker subdirectory which
> contains private files of a user. The user directories are created on the TT
> when the user's first task is assigned to this TT. But these user-directories
> are never cleaned up from the TT, even when no task of this user is running
> on this TT. This essentially leaves empty user directories hanging around on
> the TT, whose number may increase over time.
> This was originally intended to be fixed in MAPREDUCE-856, but could not be
> done because increasing complexity already stretched that issue.
