I have a Hbase cluster of 3 nodes.
Below are the hostnames and daemons running on that machines.

hbase2 - Hmaster,RegionServer, Datanode and Nodemanager

hbase 1 - RegionServer,Namenode,Datanode, ResourceManager, NodeManager

hbase 3 - RegionServer, Datanode and Nodemanager

The moment I enter the run start-hbase.sh script. It throws the below given error

2018-06-13 14:56:52,455 INFO [hbase2:60000.activeMasterManager] retry.RetryInvocationHandler: Exception while invoking getFileInfo of class ClientNamenodeProtocolTranslatorPB over hbase2/10.94.1.119:8020 after 11 fail over attempts. Trying to fail over after sleeping for 17938ms. java.net.ConnectException: Call From hbase2/10.94.1.119 to hbase2:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused.
