Yes, it's sure that the apache version of HCatalog is compiled against
hadoop1. Using this jar in an hadoop2 environment will lead to binary
incompatibility error. I think Hive community is aware of this problem.

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.
