Description

I would like to discuss the possibility of merging the prefix tree module into the hbase-server module.

Ideally, I think we should have hbase-mapreduce and hbase-storage modules, the latter one containing most of HFile code. hbase-mapreduce depends on hbase-storage so that it knows how to encode hfiles. prefix-tree belongs to hbase-storage.

prefix tree is just another DBE, although a big one, and it rightfully belongs with her sisters. The fact that the code is independent from the rest of the code base does not mean that it should have it's own module. We should keep the number of modules manageable, and stay away from hadoop trunk's one-module-per-package policy.
