Hi, Since we've run into HBASE-3872 issue, we're considering upgrade a production system from cdh3u0 to 0.90.3+HBASE-3872 patched. Is it safe to just replace the hbase directory, and restart all the regionservers and master? We have no chance to stop the whole cluster together, can we restarted the regionservers partly, ie., can cdh3u0 and 0.90.3 cooperate for a while?
Thanks and regards Mao Xu-Feng
