title: How to find installed libraries in hadoop server?
body: <p>I am currently working with hadoop server. Now , I have to train a neural network with libraries like keras, Tensorflow etc. I know there is spark libs already installed.  I just wanna check whether there are any other libs installed on hadoop server.  Our company has it's own hadoop server in a remote location.  Am not allowed to install any new libs and had to work with existing libs. Can you please let me know how to check whether there is any library that's installed in hadoop server already? </p>
