title: Cannot SSH on master node in EMR CAWS cluster
body: <p>I´m triying to connect to my master node in my EMR cluster but I get connection timed out, I already do it everything I guess, I create a key pair and set an inbound rule to accept conecctions SSH from my ip, and SSH from everywhere but I can't connect, I check the VPC and check if my cluster is not in a private network and it issn't. I don't know what else can I do. Please any clue?
  Thanks.</p>
