> As it breaks one of our design rules
> https://hbase.apache.org/book.html#design.invariants.zk.data
> We used to think hbase should be recovered automatically when all the data on zk (except the replication data) are cleared, but obviously, if you clear the meta region location, the cluster will be in trouble, and need to use operation tools to recover the cluster.
> So here, along with the ConnectionRegistry improvements, we should also consider move the meta region location off zookeeper.
