I am trying to setup a multi-node cluster using Ambari with 6 hosts created with Scaleway.com . I already did the steps described in the hortonworks Docs. I use Hdp 3.0.1 with Ambari 2.7.3.0. The steps I have already followed Generate rsa keys in master host. cat the public key to authorized_keys. changing permissions for .ssh directory and authorized_keys, id_rsa.pub and id_rsa files copied the public key to all the hosts(authorized_keys) changing permissions for authorized_keys file on all the hosts Start installing Ambari Ui wizard Copied the rsa private key of the master node to the step two ERROR 1 : I Found error in ssh connections btw hosts when i'am using Root users SCREENSHOT : Error 1 Screenshot When I'm using other user its work fine ERROR 2 : When I'm using other users i found an Error in the step 3 " Confirm Hosts " in Ambari Ui installation SCREENSHOT : Error 2 Screenshot Please dont mark this question as a duplicate.
