    I am trying to setup a HDP cluster on two CentOS 6.4 servers: server1 & server2.
    I followed every step in the manual on both boxes.
    For the server setup steps at the end such as “ambari-server setup” etc, I ran those on server1.

    On step 3.4. Confirm Hosts, it says
    server1 Failed
    server2 Success

    Since I cant post images in this forum, here are the images of what I see: http://prestonca.blogspot.com/

    I click on “Failed” and get this text:
    STDERR
    Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
    lost connection
    I dont understand how server1 can have trouble connecting to server1, which is itself?

    Hi Preston,

    In looking at the logs you posted, it appears that you did not use fully qualified domain names for the hosts in your cluster. this could be part of the problem. Also, I know it seems strange but, you do indeed need to set up passwordless ssh from the main host (server1) to itself.

    Thanks,
    Ted.
