- QUOTE: Hadoop and other applications you install on your Amazon EMR cluster, publish user interfaces as web sites hosted on the master node. For security reasons, when using EMR-Managed Security Groups, these web sites are only available on the master node's local web server, so you need to connect to the master node to view them. For more information, see Connect to the Master Node Using SSH. Hadoop also publishes user interfaces as web sites hosted on the core and task (slave) nodes. These web sites are also only available on local web servers on the nodes.
