Lavkesh Lahngir commented on LENS-1326:
---------------------------------------
One possible scenario is just after the hive restart.
SESSION_MAP will still contain session handle, but the Hive server won't be
able to get the session after the Hive restart.
> session/sessions API returning no data on GUI/API though there are active
> sessions
