We should display the session id for each HoS Application Launched, and the Query Name / Id and Dag Id for each Spark job launched. Hive-on-MR does something similar via the mapred.job.name parameter. The query name is displayed in the Job Name of the MR app.
The changes here should also allow us to leverage the config hive.query.name for HoS.
This should help with debuggability of HoS applications. The Hive-on-Tez UI does something similar.
