[jira] [Created] (STORM-2050) [storm-sql] Support User Defined Aggregate Function for Trident mode

Jungtaek Lim created STORM-2050:
-----------------------------------

             Summary: [storm-sql] Support User Defined Aggregate Function for Trident mode
                 Key: STORM-2050
                 URL: https://issues.apache.org/jira/browse/STORM-2050
             Project: Apache Storm
          Issue Type: Task
          Components: storm-sql
            Reporter: Jungtaek Lim


Currently UDAF (User defined aggregated function) is supported for standalone mode. (STORM-1709) 
Now GROUP BY for Trident mode is in progress (STORM-1434), so we would need to support UDAF for Trident mode.

Note: DDL for UDAF is supported so we don't need to address it again for Trident mode.
