Subject [jira] [Commented] (HDFS-2978) The NameNode should expose name dir statuses via JMX
Date Sat, 25 Feb 2012 00:49:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2978?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13216190#comment-13216190

Todd Lipcon commented on HDFS-2978:
-----------------------------------

I agree with Hitesh - JMX is supposed to support arbitrarily nested map structures of java
primitives, isn't it? I don't know it well, but I think we do this in other places.
