> We skipped adding GenericUDFOPNot UDF in filter expression for NOT BETWEEN operation
when vectorization is enabled because of the improvement done as part of HIVE-15884. But,
this is not handled during the conversion of filter expression to search argument due to which
incorrect predicate gets pushed down to storage layer that leads to incorrect splits generation
and incorrect result.
