Karam Singh commented on MAPREDUCE-887:
---------------------------------------
It seems the issue observed is timing. As cleanup directories and very quickly.
So seems because ls -lR command was launched ownership might changed. Checked
with commenting out code of cleanup files found permissions are set correctly
making issue as resloved invalid
> After 4491, task cleaup directory some gets created under the
> ownershiptasktracker user instread job submitting.
