Jesse Yates commented on HBASE-4336: ------------------------------------ bq. 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..... Yeah, its gonna be great! bq. Or not. Just do hbase-common and hbase-security? Can roll hbase-security back into common when time comes. I'm leaning towards this - no assurances as to when security is going to be rolled in and its really not a big deal to get rid of the module (and even not that much pain for people with patches when it is as they just apply the patches to a new root). Is that the right ticket number for rolling security in? Doesn't seem directly applicable... > 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 > 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. -- This message is automatically generated by JIRA.
