Release Note

On the server side, set hbase.meta.replica.count to the number of replicas of meta that you want to have in the cluster (defaults to 1). hbase.regionserver. meta.storefile.refresh.period should be set to a non-zero number in milliseconds - something like 30000 (defaults to 0).
On the client/user side, set hbase.meta.replicas.use to true.
