I would not recommend opening port 50070 on your cluster, as that would give the entire world access to your data on HDFS. Instead, you should follow the instructions found here to create a secure tunnel to the cluster, through which you can proxy requests to the UIs using a browser plugin like FoxyProxy: https://docs.aws.amazon.com/ElasticMapReduce/latest/ManagementGuide/emr-ssh-tunnel.html
