Subject Re: Ambari 1.6.0 installation error
Date Mon, 23 Jun 2014 14:41:24 GMT
I have had similar error. 
You need to store ssh public key of ambari server into root user of .ssh/authorized_keys file
in every host you add using web GUI. This must be done manually. Remember its root user and
not any other user.
