But other than a few obvious issues caught by the java compiler, the APIs remain the same.

Yes, the MR jobs and other apps would need to be recompiled along with this. > Where I can find the Development roadmap for HBase 0.96? Am unsure of a formal location for this. Perhaps a dev can comment. I merely try to follow as many JIRAs as I can. I do know snapshots and protobuf RPCs are some of the major work being done for this version, but others would probably know better. -- Harsh J
