Hi:

During the process to add the new host,I have received this error:

==========================

copy the public key of the ambari host to the node you are adding in the .ssh/authorized_keys and also vice versa to allow the password less authentication between the two hosts and then try register the host again.

@Roberto Sancho

The second issue is caused by the ambari repo file name. Please ensure the repo file name is ambari.repo

Hi @Roberto Sancho

Can you please post complete message? It is complaining about the previous action. Are there any messages before these lines ?

Look like the keyless ssh is not setup properly, check the document at

http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_Installing_HDP_AMB/content/_set_up_passwo...

Or install Ambari agent manually
