Description

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.
