Description

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.
