[jira] [Created] (HIVE-10344) Use newInstance to create ExprNodeGenericFuncDesc rather than construction function

Pengcheng Xiong created HIVE-10344:
--------------------------------------

             Summary: Use newInstance to create ExprNodeGenericFuncDesc rather than construction function
                 Key: HIVE-10344
                 URL: https://issues.apache.org/jira/browse/HIVE-10344
             Project: Hive
          Issue Type: Sub-task
            Reporter: Pengcheng Xiong
            Assignee: Pengcheng Xiong


ExprNodeGenericFuncDesc is now created using a constructer. It skips the initialization step "genericUDF.initializeAndFoldConstants" compared with using newInstance method. If the initialization step is skipped, some configuration parameters are not included in the serialization which generates wrong results/errors.
