Configurations for Multiple Clusters

[Eli Finkelshteyn]

Hi,
I've recently run into a situation where I'll have access to my local 
single node cluster, and development cluster, and a production cluster. 
What's the best way to work with all three of these, easily switching 
between which I want to use? I found this project 
<http://code.google.com/p/hadoopenv/wiki/README> that seems like it's 
trying to address my issue, but it hasn't been updated since 2010. Is 
this still the preferred way of managing multiple clusters, or is there 
something better (preferably something easy to install, as I'll need to 
convince others at my company to use whatever solution I find).

Thanks!
Eli
