> When we originally converted the build to maven we had a single "core" module defined, but later reverted this to a module-less build for the sake of simplicity.
> It now looks like it's time to re-address this, as we have an actual need for modules to:
> * provide a trimmed down "client" library that applications can make use of
> * more cleanly support building against different versions of Hadoop, in place of some of the reflection machinations currently required
> * incorporate the secure RPC engine that depends on some secure Hadoop classes
> I propose we start simply by refactoring into two initial modules:
> * core - common classes and utilities, and client-side code and interfaces
> * server - master and region server implementations and supporting code
> This would also lay the groundwork for incorporating the HBase security features that have been developed.  Once the module structure is in place, security-related features could then be incorporated into a third module -- "security" -- after normal review and approval.  The security module could then depend on secure Hadoop, without modifying the dependencies of the rest of the HBase code.
