In 0.96, we are going to move to PB. But HRegionInterface is still there in case someone needs it.
That means we need to maintain both implementations. It also prevents us moving to PB internally. I filed HBASE-5889 to address it. In reviewing the patch, Ted brought a good point. To those non-bundled (third-party) HBase client(s) using HRegionInterface directly, such as asynchbase, should 0.96 be a singularity too? Thanks, Jimmy
