Hadoop Administration - Two node cluster

I'm trying to install Hadoop Two node Cluster.

  1. What is the best practice to setup two node cluster in terms of running master and slaves daemons?

  2. If I run Namenode and Jobtracer as Masters in one machine and Secondary Namenode, Tasktracker and Datanode as Slaves in second machine, will it become a two node cluster?

  3. In any of the above case, can i set the replication factor as 1? and why note replication factor as 2?

You can even install Hadoop in single machine in pseudo mode.

Only for practicing

Case 1:

  1. Install NN, SNN, DN, JT, TT in master and install DN, TT in slave
  2. By this way you can configure replication factor as 2

Case 2:

  1. Install NN, SNN, JT in master and install DN, TT in slave
  2. By this you can configure replication factor as 1
