Prashant Sharma commented on MAPREDUCE-3131:
--------------------------------------------

Hadoop Mapreduce has many users exploiting its usefulness and simplicity. Some of them are
students(or non industrial users) and need it the power of mapreduce for solving their research
problems or more commonly even more trivial problems(like generating indexes or just run WordCount
;) ).

So was thinking a bit further - if I can make it (very) easy to setup a trivial(unsecured
and with default parameters) cluster(Created by sharing desktops resources - A typical scenario
among students). Our folks will have a by pass to figuring out how to setup. 

There are two approaches to this.
1. make a tar and copy it around. or( Rsync the cluster home)
2. use deb/rpm approach. 

deb and rpm setup will be more ideal but a bit nontrivial to have and will make steps more
cumbersome. But doing without package management simplifies "a few" things.  And since users
of our trivial clusters are less particular about the "Ideal" approach I propose the later.
