Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "ZooKeeper/HBaseUseCases" page has been changed by stack. http://wiki.apache.org/hadoop/ZooKeeper/HBaseUseCases?action=diff&rev1=15&rev2=16 -------------------------------------------------- == Description of how HBase uses ZooKeeper == ZooKeeper recipes that HBase plans to use current and future. By documenting these cases we (zk/hbase) can get a better idea of both how to implement the usecases in ZK, and also ensure that ZK will support these. In some cases it may be prudent to verify the cases (esp when scaling issues are identified). It may also be that new features, etc... might be identified. + + Currently, hbase clients find the cluster to connect to by asking zookeeper. The only configuration a client needs is the zk quorum to connect to. Masters and hbase slave nodes (regionservers) all register themselves with zk. If their znode evaporates, the master or regionserver is consided lost and repair begins. + + Below is some more detail on current (hbase 0.20.x) hbase use of zk: == Current Usecases == When I list the /hbase dir in zk I see this.
