Colin Patrick McCabe commented on HDFS-5473:
--------------------------------------------
I did the renaming we discussed. I also added the caching commands to
{{HdfsAdmin}}. Finally, {{listDirectives}} now returns an entry containing
info and stats. This avoids the problems we talked about earlier where the
info structure has fields that aren't usually applicable to add, modify, etc
operations.
> Consistent naming of user-visible caching classes and methods

> It's kind of warty that (after HDFS-5326 goes in) DistributedFileSystem has
> {{*CachePool}} methods take a {{CachePoolInfo}} and
> {{*PathBasedCacheDirective}} methods that thake a
> {{PathBasedCacheDirective}}. We should consider renaming {{CachePoolInfo}} to
> {{CachePool}} for consistency.
