This was done as a part of my final year project so i thought i should share this because it might be helpful to others. I assume that you know about ZooKeeper otherwise you want be reading this article right. anyway if you want to learn about ZooKeeper you can check out the ZooKeeper home page  here .

I'm also a novice in this area so i am sure i might have made a mistake or two but i couldn't get Debug As ---> JUnit Test to appear when i checkout the project using subeclipse. So this is the way that worked for me. Checkout Zookeeper Just checkout Zookeeper from svn using the following command. svn checkout http://svn.apache.org/repos/asf/zookeeper/trunk/ Build Eclipse project files Then go to ...
