Apologies in delayed response on this.
Exchange of keys procedure described in Step 6, 7 and 8 in document needs to be performed using root user.
You need to sudo its user to root and perform steps described in the doc.
Once the exchange of keys is fixed, cluster won’t prompt for password when joining the node.
Node 1- Step 6:
Node 2- Step 7:
Copy content from /root/.ssh/id_rsa.pub from NODE 1 to /root/.ssh/authorized_keys in NODE2.
Node 1- Step 8:
Copy content from /root/.ssh/id_rsa.pub from NODE 2 to /root/.ssh/authorized_keys in NODE1.
Verification: Perform ssh to Node 2. It won’t ask any password.
Hope that helps.
