In order to increase the likelihood that our planned WAL interfaces make sense, I'll try to step through how we get from the current APIs to the new ones and how we build on them to make the other WAL improvements we have planned. At the moment, I'd like this to be branch-1 / master.
Current interface/class relationship in 0.98 / branch-1 / master

Currently, Hadoop exposes downstream clients to a variety of third party libraries. As our code base grows and matures we increase the set of libraries we rely on. At the same time, as our user base grows we increase the likelihood that some downstream project will run into a conflict while attempting to use a different version of some library we depend on. While there are hot-button third party libraries that drive most of the development and support issues (e.g. Guava, Apache Commons, and Jackson), a coherent general practice will ensure that we avoid future complications. Simply attempting to coordinate library versions among Hadoop and various downstream projects is untenable, because each project has its own release schedule and often attempts to support multiple versions of other ecosystem projects. Furthermore, our current approach of taking a conservative approach to dependency updates leads to reliance on stale versions of everything. Those stale versions include
The YCSB project uses the version numbers on our releases to set expectations about the impact of upgrading for downstream users. Each release will have a version number that looks like x.y.z. Starting with version 1.0.0, these numbers map directly to:
Note that prior to version 1.0.0, minor version increments may introduce changes normally reserved for major versions.
Even when using the same major version, remember that YCSB is best suited for comparing sy
