> WebHCat should not create delegation tokens when Kerberos is not enabled

> 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
