Robert Joseph Evans commented on MAPREDUCE-3729:
------------------------------------------------
I have been thinking about this and how we can fix the issue in the code. I am
a bit confused about how /tmp/hadoop-jenkins is created by a user that is not
jenkins? unless the other person explicitly set user.name to be jenkins, or
they manually created that directory before running. Vinod or Giri, did you
look at the directories before this happened?
If I don't know what caused the bad directory t begin with I really don't have
much hope of understanding how to prevent it in the future. If the directory
was manually created then there is nothing we can do. If the user explicitly
set user.name to jenkins we can detect that, and blow up.
We cannot delete the directory after a job finishes in local mode because more
jobs could still be running.
