> HoS users have two session ids, one id for the Hive session and another id 
> for the Spark session, both are UUIDs.
> I think some improvements could be made here:
> The Spark session id could just be a counter that is incremented for each new 
> Spark session within a Hive session. Each Spark session is still globally 
> identifiable by its associated Hive session id + its own counter. This may 
> make more sense since the Hive session - Spark session has a 1-to-many 
> relationship, as in a single Hive session can contain multiple Spark 
> sessions, and each Spark session must belong to a Hive session.
> Furthermore, we should include both the Hive session id and Spark session id 
> in the console logs + the Spark Web UI.
