If you want to learn more about the networking on small to mid-size production
sites, I recommend you do a search for “Hadoop reference architectures”.
As an example, a good source of information is here:
http://en.community.dell.com/techcenter/extras/m/white_papers/20353010.aspx
(I’m not sponsoring any specific distro or vendor, you can as well read more
about HP’s Hortonworks reference architecture, Intel’s own Hadoop distro, or
MapR’s for example)

Hi all
Question regarding hadoop architecture . Generally in hadoop cluster nodes are
placed in racks and all the nodes connected to top of the rack switch . And all
these top of the rack switch connected by another switch or router ?
Is all nodes in the cluster belong to same subnet ? Or hdfs write read has
to pass through internet ?
