Yes, I have already read this document and they talking about how to configure zookeeper for hbase and ZooKeeper ensemble...
But they are not talking anything about Why Zookeeper for HBase. What i know about zookeeper ZooKeeper are storage of small bits of dynamic configuration data, locking, and group membership and perform leader election. But How it helping for HBase? Which type of information it sharing and with whom(Client, HMaster, Region Server) and how maintaining those information. which type of information leader have.
