    I am using Apache Ambari tool to setup the Hadoop Cluster environment.I am following Horton works Install guide.
    I am using RHEL5.7 version Linux servers.
    I have added the server hostnames in the /etc/hosts file properly with respective IP addresses.I have made passwordless SSH connection to all the servers.
    I am using ambari-agent-1.2.0.1-1 version.I am getting below errors while registering the hosts.Manual registration is also failing.Please suggest how to resolve this issue.

    self.httpsconn.connect()

    what do you mean by “I have made passwordless SSH connection to all the servers.” ? You need to make password less connection from your Ambari server to all the hosts.
