I do have this working on CHD4.3.0 with MR1 and Kerberos. I am finishing up a blog today explaining what was needed to get it working. I will reply with the link later today.

JC Hello All, Has anyone been successful at running hive 0.11 with Cloudera CDH 4.3? I've been able to get hive to connect to my metadb (which is in Postgres). Verified by doing a show tables..
