Hello there,   I am fairly new with unix command. Could someone help me with this?   I was trying to ssh into my cloudera EDH instance, following the instruction here. I think I got the ssh established to port 7189. However, I still cannot connect to cloudera manager from my local browser, and it gives me 'refuse to connect' error. I am running Putty on a windows machine. here is the putty log:   [ec2-user@ip-172-31-10-233 ~]$ ssh -i /home/ec2-user/cloudera/setup-default/main_key.pem -L 7189:localhost:7189 ec2-user@ec2-35-182-66-141.ca-central-1.compute.amazonaws.com Last login: Fri Jan 5 14:21:06 2018 from ip-172-31-10-233.ca-central-1.compute.internal [ec2-user@ip-172-31-10-233 ~]$ netstat -lep --tcp (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.)
