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. https://www.cloudera.com/documentation/enterprise/latest/topics/impala_dedicated_coordinator.html -- This message was sent by Atlassian JIRA (v7.6.3#76005)
