Subject [jira] [Commented] (HDFS-5556) add some more NameNode cache statistics, cache pool stats
Date Mon, 25 Nov 2013 22:42:36 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13832005#comment-13832005

Andrew Wang commented on HDFS-5556:
-----------------------------------

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.
