Description

For example, GenericUDFSplit throws ClassCastException when a non-primitive type is given.

0: jdbc:hive2://hive-hiveserver2:10000/defaul> select split(array('a,b,c'), ',');
Error: Error while compiling statement: FAILED: ClassCastException org.apache.hadoop.hive.serde2.objectinspector.StandardConstantListObjectInspector cannot be cast to org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector (state=42000,code=40000)
