Zhe Zhang updated HDFS-10584:
-----------------------------
    Hadoop Flags: Reviewed

Thanks Rakesh. +1 on the patch. I'll commit shortly.

I still think there's an issue with the 3s wait. But since it's inherited from existing code,
we should address it separately.

> The idea of this jira is to support {{mover}} tool the ability to login from a keytab.
That way, the RPC client would re-login from the keytab after expiration, which means the
process could remain authenticated indefinitely. With some people wanting to run mover non-stop
in "daemon mode", that might be a reasonable feature to add. Recently balancer has been enhanced
using this feature.
> Thanks [~zhz] for the offline discussions.
