> 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.
