    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()
    File “/usr/lib/python2.6/site-packages/ambari_agent/security.py”, line 65, in connect
    ca_certs=server_crt)

    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.
