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.
