[jira] [Updated] (HBASE-4336) Convert source tree into maven
modules
[ https://issues.apache.org/jira/browse/HBASE-4336?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ted Yu updated HBASE-4336:
--------------------------
Priority: Critical (was: Major)
Fix Version/s: 0.94.0
Raising priority.
I think this work is important so that security related classes can be packaged in their own jar.

> 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.
