Hey All, The new IHBase (indexed) contrib and the existing THBase (transactional) contrib are not compatible with each other. They both want to instantiate their own extensions of org.apache.hadoop.hbase.regionserver.HRegion and the org.apache.hadoop.hbase.regionserver.transactional.TransactionalRegion from THBase will always win.
So, at least for now, you'll have to choose between either THBase or IHBase... Cheers, Dan
