to automate copying of public key from namenode to worker nodes in EC2 Cluster in CloudFormation?
I want to do ssh hadoop-worker-1 'cat >> ~/.ssh/authorized_keys' < ~/.ssh/id_rsa.pub in my namenode but will be stopped by a password request.
I believe I need my aws-key but I'm not sure what's a reasonable way for my namenode to get it. Or find a workaround
use sshpass
that's worse lol
oh wait
Why does the worker need a key? 🤔
Seems to be required in setting up a hadoop cluster?? Unless im wrong
what aws-key does?
as in is a key for my com to ssh to my instance
