Subject [jira] [Commented] (HDFS-5473) Consistent naming of user-visible caching classes and methods
Date Wed, 20 Nov 2013 23:39:36 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13828305#comment-13828305
] 

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.

> 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.
