Figure 5.1 shows the deployment view for HBase cluster:
HBase is the master-slave cluster on top of HDFS. The classic deployment is as follows:
➢** Master node:** one HMaster and one NameNode running on a machine as the master node.
➢ Slave node: Each node is running one HRegionServer and one DataNode. And each node report status to the master node and Zookeeper.
➢** Zookeeper:** HBase is shipped with ensemble Zookeeper, but for large clusters, using existing Zookeeper is better. Zookeeper is crucial, the HMaster and HRegionServers will register on Zookeeper.
➢ Client: There can be many clients to access HRegionServer, like Java Client, Shell Client, Thrift Client and Avro Client
