I believe you still need at least Hive 0.8 to get HCatalog to work properly.
This is mainly true if you're using partitions : I ran into some issues earlier where I couldn't use partitioned tables as HCat was trying to call add_partitions with a List<Partitions> which was only implemented in Hive 0.8 (before it was add_partition with a single Partition). With my existing Hive 0.7.1 I couldn't get this stuff working due to this issue, when I switched to Hive 0.8 it worked fine. I may be wrong but that's one of the main issues I ran into.
