Jesse Yates commented on HBASE-4336:
------------------------------------
Did a bunch of the work for this already under HBASE-4438 - posted initial
patch to review board. I wasn't sure which classes we wanted to move to which
package, but set up at least the top level hierarchies and did the most of PITA
work of cleaning up the top-level pom.
Up on review board: https://reviews.apache.org/r/1965/
Right now, its a skeleton so we can easily drop in the code we want, where we
want it.
> Convert source tree into maven modules
> --------------------------------------

> Key: HBASE-4336
> URL: https://issues.apache.org/jira/browse/HBASE-4336
> Project: HBase
> Issue Type: Task
> Components: build
> Reporter: Gary Helmling
>
> 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.
