FAQ
When I try to add new through cloudera manager they are getting listed in
healthy state on the hosts tab but when I go to the jobtracker URL I don't
see this hosts listed under the nodes.

JT still sees only the old set of hosts.

Do I have to do anything extra to make this part of the hadoop cluster. I
was thinking that the cloudera manager is suppose to do that. Isn't it?

Thanks for your help,
Mark

    Are you adding the new hosts as new 'roles' to the MapReduce service? You
    have to add them to the relevant services manually.

    Thanks Philip. I just did that and I restarted all the services and I still
    don't see this node in the list.

    Sorry I now see the node in the JT (nodes show 4 now from 2) because I
    added two more.

    When I go to the box and do hadoop fs -ls /

    it shows the root directory of my "/" partition and not the "root directory
    of hdfs" I see from other working data nodes.

    You need to click on "deploy client configuration", probably.
