Gary Helmling commented on HBASE-4336:
--------------------------------------
@stack
The security profile stuff is part of the current HBASE-2742 patch. It does 2
things: changes hadoop.version to a 0.20.205.0 snapshot I've built, and adds
the security/src/(main|test)/java paths to the build. If we're building
against all "secure" hadoops, then we may be able to just have it do the second
and be usable in combination with any of the hadoop profiles.
Longer term, I still think we'll want security in its own module so it can be
packaged and enabled separately. But with the profile, modularizing at least
isn't a blocker for it.

> 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.
