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.

Hmaster is not running. RegionServers are working fine

Looks like your Namenode is not running. Start the NameNode first and then try starting HBase master.
Also, it is better to give proper hostnames instead of hbase1, hbase2 etc.
