Description

Currently, when a simulator or benchmark is running and simulating hadoop jobs using rumen data, and rumen's runtime system is used to get execution times for the tasks in the simulated jobs, rumen would use some ad hoc code, despite the fact that rumen has a perfectly good interpolation framework to generate random variables that fit discrete CDFs.

We should use the interpolation framework.
