> Extensions using CLIService session handles should be able to restore the
> session from the handle.
> Apache Lens depends on a fork of hive and that fork has such a capability.
> Functionality added: Restoring a session. A session opened once is lost once
> the cli service is re-created. There may be some operation going on in that
> session at the time the service is restarted. It's useful to be able to
> restore a previously existing session.
> Have added code in CLIService for that effect. Have also added a test class.
