[jira] Commented: (HADOOP-4675) Current Ganglia metrics implementation is incompatible with Ganglia 3.1

    [ https://issues.apache.org/jira/browse/HADOOP-4675?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12683655#action_12683655 ]

-----------------------------------------

Hey Steve,

1) This does not break Ganglia 3.0.  It gives a subclass of the Ganglia 3.0 implementation that is compatible with 3.1.

2) I'll have to work on this - we're currently using the patch for 0.19, so I haven't looked at the DNS class yet.  Can you give an example (or fix the patch yourself) :)?

> Ganglia changed its wire protocol in the 3.1.x series; the current implementation only works for 3.0.x.
