Subject [jira] [Created] (MAPREDUCE-5458) Jobhistory server (and probably others) throws HTTP 500 error if keytab fails
Date Wed, 14 Aug 2013 20:57:47 GMT
Allen Wittenauer created MAPREDUCE-5458:
-------------------------------------------

             Summary: Jobhistory server (and probably others) throws HTTP 500 error if keytab
fails
                 Key: MAPREDUCE-5458
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5458
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobhistoryserver
    Affects Versions: 2.1.0-beta
            Reporter: Allen Wittenauer


I had a situation where the job history didn't renew its kerberos credentials (still verifying
that problem).  If a user connects to the web UI at a point when the server can't talk to
HDFS, it shows the user a 500 error rather than giving something meaningful.
