> We need to be able to set logging per HS2 session.
> The client often uses the map-reduce completion matrix (Execution) that shows
> up in Beeline to debug performance. User might not want the verbose log view
> all the time since it obfuscates the Execution information. Hence the client
> should be able to change the verbosity level.
> Also, there are 2 levels of verbosity at HS2 logging and not 3. The users
> might want Execution + Performance counters only - so that level needs to be
> added.
> So for logs, the user should be able to set 3 levels of verbosity in the
> session, that will override the default verbosity specified in the
> hive-site.xml file.
> 0. None - IGNORE
> 1. Execution - Just shows the map-reduce tasks completing
> 2. Performance - Execution + Performance counters dumped at the end
> 3. Verbose - All logs
