You won't have this directly. /hbase/rs contains the regionservers that are online. When a regionserver dies, hbase (or zookeeper if it's a silent failure) will remove it from this list. (And obviously this is internal to hbase and could change or not at any time :-) ). But technically you can do as hbase does and set a zookeeper watcher in this znode.
What do you want to achieve exactly?
