stack commented on HBASE-4336:
------------------------------
bq. I'm for having it now since we know we are going to need common and
security isn't yet in (and could still be required if we want to compile
against older versions).
One suggestion would be to have this issue predicated on security being rolled
back into core (hbase-5372) -- then we could do w/o having to mess with a
security module.
Or not. Just do hbase-common and hbase-security? Can roll hbase-security back
into common when time comes.
I'm excited about this one. I liked the notion by Mat Corgan that we'd have an
hbase-hregion module and then there'd be an hbase-wal so Li Pi can experiment
standalone w/ multiple WALs at the one time, etc., etc. The new client would
be one.....

> 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.
