Users can set non-writable permissions on temporary files for TT and can abuse disk usage.
------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-896
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-896
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
            Reporter: Vinod K V


As of now, irrespective of the TaskController in use, TT itself does a full delete on local
files created by itself or job tasks. This step, depending upon TT's umask and the permissions
set by files by the user, for e.g in job-work/task-work or child.tmp directories, may or may
not go through successful completion fully. Thus is left an opportunity for abusing disk space
usage either accidentally or intentionally by TT/users.
