Subject [jira] [Created] (HDFS-3691) UserGroupInformation#spawnAutoRenewalThreadForUserCreds dumps shell output to stdout / stderr
Date Thu, 19 Jul 2012 22:55:35 GMT
Colin Patrick McCabe created HDFS-3691:
------------------------------------------

             Summary: UserGroupInformation#spawnAutoRenewalThreadForUserCreds dumps shell
output to stdout / stderr
                 Key: HDFS-3691
                 URL: https://issues.apache.org/jira/browse/HDFS-3691
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 2.0.1-alpha
            Reporter: Colin Patrick McCabe
            Priority: Minor
             Fix For: 2.2.0-alpha


UserGroupInformation#spawnAutoRenewalThreadForUserCreds tries to renew user credentials. 
However, it does this even if the kerberos ticket cache in question is non-renewable.

This leads to an annoying error message being printed out all the time.
