Karl, Sorry but could you let me know which hadoop version is being used, and any compatible issue? It seems Hbase 0.90.2 and 0.90.3 are compatible only on 0.20-append only.

We currently use the supplied ThriftServer in Hbase. In my initial testing for the upgrade, I've not seen any issues using code that was generated/compiled against the earlier versions of hbase/thrift and simply pointing them at the latest ThriftServer supplied with .90.3 I don't see thrift mentioned specifically in the upgrade topic in the book, and couldn't find any directly related topics on the mailing list, so I would like to just verify this is the expected result. Am I missing something subtle that could cause issues later? Would updating client code to use Thrift .5 provide a performance (or some other nice) improvement? Thanks, -Karl
