hi Ramaswamy,

As you have installed Cloudera, you don't need to perform any other steps. Looking at the points looks like the installation is skewed because of java path setup and ssh key generation.

We are using cloudera because we don't want the students to spend time in installation.

You can directly start executing mapreduce programs.

You can't format if your using vmplayer to run cloudra Hadoop. To run the formatting commands you need to setup a local Hadoop environment in Ubuntu os

Sure. Thanks All. However, Running jps command doesn't list hadoop daemon processes. How do know the name and other nodes are running from CLI?.
