Hi Shushant, Ensemble is the set of all ZooKeeper servers. quorum is a subset of an ensemble that contains more than half of the servers (more accurate servers that are not of type 'observer') which are required for ZooKeeper service to be available. >From http://hbase.apache.org/0.94/book/zookeeper.html: "You must at least list the ensemble servers in hbase-site.xml using the hbase.zookeeper.quorum property." i.e., hbase.zookeeper.quorum is the list of ensemble (the parameter name is misleading). you can't list a quorum as it this list is decided in real time from all none-observer servers that are up and connected to each other. Hope this helps.
