Subject [jira] [Created] (MAPREDUCE-3475) JT can't renew its own tokens
Date Mon, 28 Nov 2011 16:05:40 GMT
JT can't renew its own tokens

                 Key: MAPREDUCE-3475
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3475
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
    Affects Versions:
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp

When external systems submit jobs whose tasks need to submit additional jobs (such as oozie/pig),
they include their own MR token used to submit the job.  The token's renewer may not allow
the JT to renew the token.  The JT log will include very long SASL/GSSAPI exceptions when
the job is submitted.  It is also dubious for the JT to renew its token because it renders
the expiry as meaningless since the JT will renew its own token until the max lifetime is

After speaking with Owen & Jitendra, the immediate solution is for the JT to not attempt
to renew its own tokens.
