> Key: HDFS-4780
> URL: https://issues.apache.org/jira/browse/HDFS-4780
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 3.0.0, 2.0.5-beta, 0.23.8
> Reporter: Kihwal Lee
> Assignee: Robert Parker
> Priority: Minor
>
> A number of components call reloginFromKeytab() before making requests. For StandbyCheckpointer and SecondaryNameNode, where this can be called frequently, it generates many WARN messages like this:
> WARN security.UserGroupInformation: Not attempting to re-login since the last re-login was attempted less than 600 seconds before.
> Other than these messages, it doesn't do anything wrong. But it will be nice if it is changed to call checkTGTAndReloginFromKeytab() to avoid the potentially misleading WARN messages.
