Rajat Khandelwal commented on HIVE-12777:
-----------------------------------------
Agree with you on that. Maybe the name can be changed to
`retrieveSessionHandle` or something. However, notice that the person who's
trying to retrieve then handle, had persisted the handle. The same person can
persist the jars, functions etc as and when required, so that they can be used
at the time or restore. The full-fledged restore feature that I mentioned
earlier will contain the steps you mention. This feature is just for the users
of CLIService.
> Add capability to restore session in CLIService and SessionManager

> 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.
