        Setup Multi Hbase master on Hadoop Cluster to avoid single point failure. When active master failed/down for some reason exceed timeout we expected, backup master will be active and take over the role of master, see the value of zookeeper.session.timeout.

$cat /usr/lib/hbase/conf/hbase-site.xml
<name>zookeeper.session.timeout</name>
<value>180000</value>
<description>ZooKeeper session timeout. HBase passes this to the zk quorum as suggested maximum time for a session.In milliseconds.</description>
</property>

  • Test scenarios:

hadoop01.cluster.2hei.net (Hbase master)
hadoop02.cluster.2hei.net (Hbase backup master)
