Installation failed. Failed to authenticate.

Hi I am trying to install cdh and its associated packages in my centos 7 machine. when I was installing the

cloudera manager I got the errorInstallation failed. Failed to authenticate.. when i searched the community I can see that its due to ssh misconfiguration. When I tried to run ssh@localhost I have no problems .Please help me how to proceed further.

Re: Installation failed. Failed to authenticate.

We need more information on which step is failing. i am assuming that the agents are failing during the Cluster install wizard. If this is the case you will need to follow our requirements docs:

"One of the following, configured during initial installation of Cloudera Manager:

  • Direct access to root user using the root password.
  • Direct access to root user using a SSH key file.
  • Passwordless sudo access for a specific user. This is the same requirement as the installation of CDH components on individual hosts, which is a requirement of the UNIX system in general.

You cannot use another system (such as PowerBroker) that provides root/sudo privileges."
