Devaraj Das commented on MAPREDUCE-1322:
----------------------------------------
bq. Isnt MAPREDUCE-1139 the right fix?
That fix would address this issue as well but I'd like the staging directory to
be defined in mapred-default.xml anyway.
bq. Error Launching job : chmod: cannot access
`/tmp/hadoop/mapred/staging/dummy44913967/.staging/job_local_0001': No such
file or directory
The attached patch should fix this problem (this happens due to the fact that
the same /tmp/hadoop directory is being read/written by multiple users).
