add hadoop servers to same cluster(Master-Slave )

I have 2 hadoop pseudo(standalone) servers, which I created for testing purposes. Now I want to club the two servers into one cluster and make this a Master-Slave configuration. Is there anyway to achieve this? Thanks in advance.

Step 1 Determine which pseudo you want to be master. Once decided add master machine name in file

$hadoop_home/conf/master

Step 2

If u want other pseudo as well as master machine to act as DataNodes then add these machine names in file

$hadoop_home/conf/slaves

Step 3

Make SSH password less connection between master and slave. And change 

/etc/hosts

file if necessary if they are getting connected.

Step 4 Now prepare the hadoop MultiNode Cluster to start

Format namenode 

$hadoop_home/bin/hadoop namenode -format

Start the cluster

$hadoop_home/bin/start-all.sh
