Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The following page has been changed by PatrickHunt: http://wiki.apache.org/hadoop/ZooKeeper/Glossary New page: ==Glossary of ZooKeeper Terms== * Ensemble : group of cooperating ZooKeeper server instances * Quorum : a minimum subset of the ensemble necessary, for example, to commit an operation or to support a leader. In our case, a quorum is always a majority of servers of the ensemble.
