stack commented on HBASE-4336:
------------------------------
@Gary How is the security as a profile going? You still need modularized hbase
build? Going forward won't the hadoops we have checked all be 'secure'
hadoops; e.g. 0.92 will likely ship with 0.20.205.x?
@Jesse You asking if this is a good time to modularize? If so, it never is (I
think you say that above -- smile). I'd say we do an announcement up on the
list to give folks a window in which they can scramble to get patches in -- two
weeks of a window? Then I'd say we'd hack it in (maybe a bit of githubbing to
get the initial patch worked out).
> 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.
