Currently, Hive has been released to 1.1.0. Also from Hive 0.14.0, it changed hcatalog package name. But Tajo just provides hive 0.12.0 and hive 0.13.1. Thus, we need to improve hive compatibility. For this issue, I’ll remove hcatalog dependency. It’s not problem because hcatalog just has been used to find hive data types and Tajo can find right data types with Hive serdeConstants.
