Before preparing node-2 and node-3, each node of your
cluster must have the same configuration information. Node-2 runs as a backup Master server
and a ZooKeeper instance.
Download and unpack HBase on node-2 and node-3.
Copy the configuration files from node-1 to node-2 and node-3.
Copy the contents of the conf/ directory to the conf/ directory on node-2 and
node-3.
