Hi,

I am trying to add new node to the cluster from Ambari, I am providing host IP, username & ssh key.

Getting this error in ambari

Anyone know what I missing here ?

This is on Ambari : 2.2.1.12 & HDP 2.4.2.4-5

Thanks

Hi @roy p,

Can you reach the new node from the Ambari server through it's FQDN? If not, check your etc hosts. Can you password-less ssh into the host your trying to add from any of the other hosts already in the cluster?

If you tried that already, check out the suggestions here - https://community.hortonworks.com/questions/10473/can-not-deploy-to-hosts.html

[#3]

I am able to ssh from one of the head node to this new host. If I am providing ssh user & ssh key, then why I need password-less ssh ?

[#4]

I just wanted to confirm you could manually "ssh -i" from the Ambari node to the new and vice versa. To your point, using the ssh key removes the need to provide a password.

I also recommend a yum update or equivalent on the node your trying to add. Ensuring the repos are freshest and packages are the the latest levels (same as the Ambari server).

[#5]

For adding the host

1) Login in to Ambari with admin and go to host.

2) Register the host with Private key (id_rsa) and give user name where you installing from target host

or ssh need to be enabled without password ( normally use "root" or other)

3) By default it will install the clients on new host and do the pre-requisite check.

[#6]

Thats what I am doing.

1. Going to Ambari as Admin user.
2. Add Host
3. Providing ip, ssh username, private key for the ssh user

@roy p

Any luck after updating the yum update and verifying /etc/hosts?
