HBase High Availability
If you are working in an HDP 2.2 or later environment, you can configure high availability for HBase by adding an HBase master component. During the Apache HBase service installation and depending on your component assignment, Ambari installs and configures one HBase Master component and multiple RegionServer components. To configure high availability for the HBase service, you can run two or more HBase Master components. HBase uses ZooKeeper for coordination of the active Master in a cluster running two or more HBase Masters.
