Hello, I am new to Hadoop. I have installed Ubuntu i386 on my VM and want to debug hadoop. Can you please guide me as to which stable release should I download and exactly how should I use ANT debugger to debug hadoop. Also, I would like to know how the MapReduce interacts with other FileSystems like KFS, S3, etc. I went through the code but did not get how exactly the JobTracker on S3 is running MapReduce. I want to implement another file system similar to S3 thus, wanted to know how to leverage MapReduce(MR) on my cloud store so that a Hadoop client is able to run MR on my cloud store.
Thanks & Regards, Nikhil
