Varun Vasudev updated YARN-2440:

    Attachment: screenshot-current-implementation.jpg

Screenshot with the CPU usage in the current implementation. In my 
yarn-site.xml, I had set yarn.nodemanager.resource.cpu-vcores to 2. The python 
script is taking up as many cores as it can.

The quota for the yarn group was set to -1.
