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. > Consuming published Hive HCatalog artificats in a Hadoop 2 build environment > fails > ---------------------------------------------------------------------------------- > > Key: HIVE-7349 > URL: https://issues.apache.org/jira/browse/HIVE-7349 > Project: Hive > Issue Type: Bug > Components: HCatalog > Affects Versions: 0.13.0 > Reporter: Venkat Ranganathan > > The published Hive artifacts are built with Hadoop 1 profile.
