Prepare node-2 and node-3 for Hbase

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.
  1. Download and unpack HBase on node-2 and node-3.
  2. Copy the configuration files from node-1 to node-2 and node-3.
  3. Copy the contents of the conf/ directory to the conf/ directory on node-2 and node-3.
