We had a lot of requests for open sourcing MP but I don't think it would have been very useful. The code itself is interesting to look at but the system is designed for very large data sets, has a lot of moving parts to manage and configure, and would be very difficult to operate at anything below at least double-digit petabytes. MP was designed for multiple exabytes across many data centers and geographic regions. A different system design (or just using S3) would be more appropriate for use at smaller scales.
