- listCachePools now returns a list of CachePoolEntry objects, which contain CachePoolInfo and CachePoolStats. This is similar to how we handle listDirectives.
- CachePool now contains an implicit list of all the CacheDirective objects in that pool. Currently, this just makes deleting a cache pool faster. In the future, this will be useful for improving the cache replication monitor.
- rename some places where we were using the word "entry" but really we should be saying "directive"
- validate that we can't set negative CachePool weights. Throw InvalidRequestException rather than plain IOE when asked to do this.
- CacheReplicationMonitor#rescanCacheDirectives: fix invalid javadoc comment.
- add NameNode statistics for total cluster cache capacity and usage in bytes.
- CacheManager#processCacheReportImpl: since we no longer send the genstamp of cached blocks on the wire in cache reports, there is no need to check it here.

Patch looks good. It'd be easier to review if these renames were in a separate JIRA, but I managed. There's also going to be some conflict with HDFS-5430, it'd be nice if that could go first since rebasing after a big rename is challenging.
- Did you want to expose the new CachePool stats in the CacheAdmin output? It'd be nice.
- Need tests for the new CachePoolStats object, and the NN's new CacheUsed stat
- I added some tests for the new DN stats
the Cache pool stats aren't hooked up yet (I am planning on doing that in a follow-on). This is just setting up the types and protobuf changes. Let's wait on CacheAdmin support until we get that straightened out.
I missed this before, but are we sure we want to add new stats to NameNodeMXBean rather than FSNamesystemMBean? It's a public stable interface, so modifications here are not backwards compatible.
I'd also like to see a test a la TestNameNodeMetrics verifying that the new NN metrics show up. It should be straightfoward to insert a few more checks in an existing caching test or check method. We can wait on CachePoolStats tests until they're hooked up.
cache is logically a per-cluster thing, not a per-namesystem thing. So I think it does belong in NameNodeMXBean, just like getPercentUsed, etc.
I will check up on adding this to TestNameNodeMetrics
