> Key: HIVE-10344
> URL: https://issues.apache.org/jira/browse/HIVE-10344
> Project: Hive
> Issue Type: Sub-task
> Components: CBO
> Reporter: Pengcheng Xiong
> Assignee: Pengcheng Xiong
> Fix For: 1.2.0
>
>
> 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.
