Allen Wittenauer resolved MAPREDUCE-1652.
-----------------------------------------

    Resolution: Duplicate

I'm going to dupe this to MAPREDUCE-2041 since:

a) there are more people on it
b) the error message should get fixed when the race condition gets fixed

> If task cannot create job-acls.xml in userlogs/$jobid/task-attempt-dir(because of disc being full, OR disc has gone bad, etc), then task should emit a better error message instead of failing with FileNotFoundException in writeJobACLs().
