Developing MapReduce

I use eclipse. Is this http://wiki.apache.org/hadoop/EclipsePlugIn
still the best way to develop mapreduce programs in hadoop? Just want
to make sure before I go down this path.
Or should I just add hadoop jars in my classpath of eclipse and create
my own MapReduce programs.
Thanks

When you download the hadoop in its dist(i don't remember  exact name) there is a related plugin.
Go and get it from there.

Hi Mohit
        I'm really not sure how many of the map reduce developers use the map reduce eclipse
plugin. AFAIK majority don't. As Jignesh mentioned you can get it from the hadoop distribution
folder as soon as you unzip the same. 
My suggested approach would be,If you are on Windows OS, you can test run your map reduce
code in two ways.
-set up cygwin in Windows, atop you can set up hadoop and related tools. It is a little messy.
-Use a linux VM image. I'd recommend  Cloudera test VM,as it comes pre configured with the
whole hadoop technology stack. It really segregates the developer from the hassles of installing
the hadoop tools and making them up and running.
In Linux or Mac you can just add the hadoop jars to your class path and run the driver class
as just how you run a java class within eclipse.(Here hadoop would be on standalone mode).
Hope it helps!...
