Hi Fanbin, the host should be the external IP of your master node. However, usually the port 5005 is not open in EMR (you could any other open, non-used port).
Alternatively, you could use a SSH port forwarding [1]: ssh -L <some port>:<emr address>:5005 And then connect to localhost:<some port> in your IDE.
