I just tried running hbase 0.20.1 on hadoop 0.20.0 and it seems to work fine (tried an upload). I tried connecting to hbase 0.20.0 cluster from an hbase 0.20.1 client. ZK seems fine. I can do a zk_dump using zk client (I did a diff between what was in 0.20.0 hbase and 3.2.1 zk and there have been quiet a few changes). There does seem to be an issue with 0.20.1 hbase connecting to 0.20.0 at least in shell (missing method getRegionsAssignment([B)). Is the latter a problem for you Ken?
