Hello, I am very new to networking and also very new to Hadoop. I have some questions regarding installing / running a small (2x namenode, 3x datanode) Hadoop cluster and how to connect the small cluster with the rest of our environment. We have 2 networks - a 'public' network (which is really not public at all, just allows desktops, etc. to connect to it), and a 'cluster' network which is where we connect our cluster computing together. We would like to put our Hadoop cluster in the 'cluster' network, but I'm unclear as to how the 'public' network connects to this. Is it correct to think that this is where 'edge nodes' come in to play? We can have nodes (can they be virtualized?) which sit in both the 'public' and 'cluster' networks so that members of the public network can connect to these edge nodes and access the Hadoop cluster behind the scenes? ...
