Subject [jira] [Created] (HADOOP-8725) MR is broken when security is off
Date Fri, 24 Aug 2012 01:46:42 GMT
Daryn Sharp created HADOOP-8725:

             Summary: MR is broken when security is off
                 Key: HADOOP-8725
                 URL: https://issues.apache.org/jira/browse/HADOOP-8725
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 0.23.3, 2.1.0-alpha, 3.0.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp
            Priority: Blocker

HADOOP-8225 broke MR when security is off.  MR was changed to stop re-reading the credentials
that UGI had already read, and to stop putting those tokens back into the UGI where they already
were.  UGI only reads a credentials file when security is enabled, but MR uses tokens (ie.
job token) even when security is disabled...
