Using this jar in an hadoop2 environment will lead to binary incompatibility error. I think Hive community is aware of this problem. https://issues.apache.org/jira/browse/HIVE-7349 On the other hand. The cloudera Hcatalog jar is compiled against hadoop2, thus works with hadoop2 environment. But using cloudera jar in a hadoop1 environment will lead to binary incompatibility error. I guess one way to solve this is to add a vendor-specific hcatalog-module for users who want to use hcatalog in hadoop2 or we need to wait until hive community publish 2 artifacts in maven for both hadoop1 and hadoop2.
