>                 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

>         Attachments: HDFS-4780-branch0.23v1.patch, HDFS-4780v1.patch
> 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.
