Ambari automatic registration failed (Step 3: Confirm Hosts)


Log attached : ambari-server.txt

I am trying to install a 3 node cluster using ambari

Machine 1 : Master Node + Local repository + Ambari Server

Machine 2 and 3 : Data Node

Local repository is on the same system as master node and ambari-server.

I am using ambari server 2.4.2 to install hdp 2.5

repolist command lists :

1) HDP-2.5


3) Updates-ambari-

I am using passwordless SSH for user hdpuser. This is the logged in user in the system. It is also sudo user. I have confirmed that password SSH works for this user.

After lot of install failures, I am trying to install ONLY master node to understand problem.

I am not get past auto-registration step itself.

I am getting lot of messages like following. Not sure if they are "normal" or cause of problem :

Finally solved!! The problem was that even if SSH was setup without password, sudo user ('hdpuser') was setup with password (This means for sudo commands, i was prompted for password).

I modified sudoers entry to make it password less on all cluster machines. That did it!
