That should be the case but to be sure I'd run a check. We don't have a script for you just yet but should be easy enough to list all hfiles under hbase rootdir and feed them to the hflie tool -- see '8.7.5.2.2. HFile Tool' in the reference guide -- and have it output metadata. That'll tell you for sure. St.Ack
