I see that you are getting "No Such file or directory" error. So first you will need to find the AWS ssh key on your local machine to do a successful SCP.

Or if the SSH key is already setup then you can simply run the command without -i option as following to see if it works:

# scp root@namenode:/var/log/ambari-server/ambari-server.log   /tmp

.

Thanks a lot @Jay SenSharma for your help.
Today when i was login to my AWS machine. it does not start all service and give me an error 8080:Port and Ambari Server issue.
I just Go inot @nameNode
and write command : Service Iptables Stop
and both issue solves 🙂 🙂
Hope it will work smoothly.
Thanks again
