Enis Soztutar commented on HBASE-4336:
--------------------------------------
bq. I think an hbase-common, hbase-security and hbase-core packages would be a
reasonable
+1 to that. At least getting the module structure in place will help us a lot.
After that we can gradually attack client-server separation.
Since 0.96 is the singularity, should we make client side module a blocker? It
seems we might have to break BC for this as well.

> Key: HBASE-4336
> URL: https://issues.apache.org/jira/browse/HBASE-4336
> Project: HBase
> Issue Type: Task
> Components: build
> Reporter: Gary Helmling
> Priority: Critical
> Fix For: 0.96.0

>
> 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.
