Subject [jira] [Commented] (MAPREDUCE-3729) Commit build failing TestJobClientGetJob, TestMRWithDistributedCache, TestLocalModeWithNewApis
Date Mon, 12 Mar 2012 16:35:39 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3729?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13227667#comment-13227667

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.
