Hey.   Having the list of all the ports being used helped me a lot in the next problem I faced. After the deployment went fine I went back to the cloudera manager screen and the main page was not showing the graphs and statistics. There was a message saying time-out to the host. So I added the list of all the Cloudera ports to the security group and now the Cloudera manager is showing the graphs.   So adding the ports into the secuirty group fixed the issue of not seeing the graphs in Cloudera manager. Any chance you know which port is responsible for graph communication ?   Thanks a lot guys, Kudos !   ... View more
