In hadoop All racks belongs to same subnet !
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 ?
Regards
Navaz

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)
