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