I have two hosts 192.168.1.15 (Master) and 192.168.1.16 (Worker)

These two hosts have exchanged public keys so they have free access to each other.

But when I do <spark home>/sbin/start-all.sh from 192.168.1.15 I still get 

192.168.1.16: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

any thoughts why? or what i could check to fix this.
