> There are at least 3 Schedulers in Hadoop today: Default, Capacity, and Fairshare. Over
time, we're seeing a lot of functionality common to all three. Many bug fixes, improvements
to existing functionality, and new functionality are applicable to all three schedulers. This
trend seems to be getting stronger, as we notice similar problems, solutions, and ideas. This
is a proposal to detect and consolidate such common functionality.
