Setting up a Hadoop cluster where nodes are spread over the Internet

[Lucas Nazário dos Santos]

Hello,

Can someone point me out what are the extra tasks that need to be performed
in order to set up a cluster where nodes are spread over the Internet, in
different LANs?

Do I need to free any datanode/namenode ports? How do I get the datanodes to
know the valid namenode IP, and not something like 10.1.1.1?

Any help is appreciate.
