------------------------------------
Could we have description of what the feature is please? I don't understand
what we are trying to achieve here. Are we trying to restore a session that's
lost? How does it get lost? Where do we restore it from? What are the use
cases? How does this benefits Hive users?
> Add capability to restore session

> Extensions using Hive session handles should be able to restore the hive
> session from the handle.
> Apache Lens depends on a fork of hive and that fork has such a capability.
> Relevant commit:
> https://github.com/InMobi/hive/commit/931fe9116161a18952c082c14223ad6745fefe00#diff-0acb35f7cab7492f522b0c40ce3ce1be
> Functionality added: Restoring a session. A session opened once is lost once
> the cli service is restarted. 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.
