-------------------------------------
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.
