I've been reading about hadoop and multi-node setups, and it says in the documentation that you must have a JVM and hadoop software already running on those nodes.

My question is, do people install this software on each of these computers individually? or is there a software solution that automates this process?

I've also read about KVM switches, but I'm not sure whether this is what people usually use in these situations.


It depends on your architecture. On UNIX systems, tools like puppet are really usefull : http://www.puppetlabs.com/ .

You have also deployement tools on windows systems throw groups management.

Then, you'll also need a monitoring tool.

I can't be really precise, as long as you don't give many information to build on.
