Currently, It is not supported to use script(e.g. python) to process array type
or map type, it will complain with below message:
{{org.apache.spark.sql.catalyst.expressions.UnsafeArrayData cannot be cast to

{{org.apache.spark.sql.catalyst.expressions.UnsafeMapData cannot be cast to
java.util.Map}}
