Thanks David. But do I need to install virtualenv on every node in hadoop cluster? Actually I am not very sure whether same namenodes are assigned for my every hadoop job. So how shall I proceed on such scenario.

Thanks for your inputs.

You can create a virtualenv, and install packages on it without
needing root access. To minimize trouble, you can ensure it uses the
system packages when available. Here are instructions on how to
install it:

This does not require root access, but it is probably good to check
with the sysadmins to make sure they are fine with it.
