> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 0.22.0
> Reporter: Todd Lipcon

> This is an amendment to MAPREDUCE-2096 that's found in Yahoo's 0.20.100
> branch.
> This bug causes task failures in the following case:
> - Cluster is not set up with LinuxTaskController (ie not secured cluster)
> - Job submitter is not the same as the user running the TT
> - Map output is more than one spill's worth
> The issue is that UserGroupInformation's view of the current user is the job
> submitter, but on disk the spill files will be owned by the TT user. SecureIO
> will then fail when constructing the spill record.
