Since the INET4 type is not handled properly during cast, InvalidCastException occurs as follows.
ERROR: INET4 value cannot be casted to INET4
org.apache.tajo.exception.InvalidCastException: INET4 value cannot be casted to INET4
Since the patch includes a very trivial change, I put it at Jira directly.
Hyunsik Choi thanks for your quick review!
