Thanks a lot Amareshwari!
Though I have gone through this code earlier I was unsuccessful at that
time. Now I went through it again, and retried. Now it's working fine.
One thing that I would point out here is that (for anybody else who may
refer to this thread) that after unarchiving the archive file hadoop doesnot
change it's name e.g. If you distributed sample.tar, it will be unarchived
to a "sample.tar" directory and not "sample".
Thanks Again,
Akhil
