How to log into slaves


One can log into the slave nodes using Agent Forwarding by SSH. Suppose that I find in the YARN log
java.nio.channels.CancelledKeyException

java.io.IOException: Connection reset by peer
...

I would like to SSH to the slave ip-172-31-xx-xx.ec2.internal to check the logs. To do so, firstly we have to add EMR identity to the agent
