Subject [jira] [Created] (HIVE-10992) WebHCat should not create delegation tokens when Kerberos is not enabled
Date Fri, 12 Jun 2015 19:53:00 GMT
Eugene Koifman created HIVE-10992:
-------------------------------------

             Summary: WebHCat should not create delegation tokens when Kerberos is not enabled
                 Key: HIVE-10992
                 URL: https://issues.apache.org/jira/browse/HIVE-10992
             Project: Hive
          Issue Type: Bug
          Components: WebHCat
    Affects Versions: 0.14.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


TempletonControllerJob.run() method does
{noformat}
      Token<DelegationTokenIdentifier> mrdt = jc.getDelegationToken(new Text("mr token"));
      job.getCredentials().addToken(new Text("mr token"), mrdt);
{noformat}

it should only do this if UserGroupInformation.isSecurityEnabled().

For long running jobs submitted via WebHCat (> 24 hours), this token is cancelled automatically
(see YARN-2964) for the LaunchMapper while the child job may still be running.

Then errors like this may happen
