I have some problem with ambari installation on 3 nodes cluster.
When I start installation on nodes it fails with empty error message.
There are no log messages, no ui messages.
I have set up ssh connection with public keys, disabled iptables.
And I do not have idea what can be go wrong in this situation.
Screenshot in attachement.
It looks a permission issue, assuming you followed the host preparation steps on all the hosts especially on the Ambari host ,hint NEVER ignore any point in the official document !
# ssh-keygen # chmod 700 ~/.ssh # cat ~/.ssh/id_rsa.pub >> authorized_keys # chmod 600 ~/.ssh/authorized_keys
And copied the authorized_keys to all the other hosts in ~/.ssh/authorized_keys
Can you log on the other hosts successfully without a password from the ambari server? eg
# ssh root@host_b # ssh root@host_c
Does your /etc/hosts entries on all the host have the 3 IP's/hostname/alias ?
In the Add Host Wizard
Target Host including the Ambari server should be FQDN
Host Registration Information ...copy and paste the ssh private key
SSH User Account root
SSH Port Number 22
