[jira] [Created] (HIVE-21524) Impala Engine

David Mollitor created HIVE-21524:
-------------------------------------

             Summary: Impala Engine
                 Key: HIVE-21524
                 URL: https://issues.apache.org/jira/browse/HIVE-21524
             Project: Hive
          Issue Type: New Feature
    Affects Versions: 4.0.0
            Reporter: David Mollitor


Now that Impala has "dedicated coordinator" capability, it could be interesting to pair HiveServer2 instances with Impala dedicated coordinators on the same localhost.  A client could request an 'impala' execution engine and subsequent queries would be routed to the local coordinator.

{code:sql}
set hive.execution.engine=impala;
{code}

This would allow clients seamless access to both capabilities without needing different connections or drivers, Hive would also be a central location for auditing and authorization.
