Hi, I have the same experience; that is, that section 5.2 in the installation guide doesn't address password-free ssh correctly.
I find it easiest to set up the ~/.ssh/authorized_keys file on the server node first by copying ~/.ssh/id_dsa.pub values from the slave nodes into that file. Then, I simply use scp to copy ~/.ssh/authorized_keys to the agent nodes. Finally, I find that you have to do the following on each node: chmod 755 ~/.ssh chmod 600 ~/.ssh/authorized_keys cd ~/.ssh chmod 700 .. (that's two periods) Sincerely, Gunnar Innovation is a team sport - Michael Idechik, vice president of advanced technologies, General Electric From: Ravindranath Akila [mailto:[email protected]] Sent: Thursday, March 21, 2013 2:52 PM To: [email protected] Subject: Passwordless login from master as well Could you please update the documentation to include that Passwordless login is required from masters to slaves as well? Also include use of ssh-copy-id? Just thought of suggesting based on my experience with Ambari. Finally got the cluster running B-) -Ravindranath Akila
