zhangwei commented on HADOOP-4675:
----------------------------------
I test the patch OK.And I suggest to add the group attribute in the extra data
the metric in Ganglia3.1.* has the attribute,so i think to put the prefix of
the metric name to the group name.
for example:
metric :dfs.namenode.FilesCreated --> group: dfs.namenode
> Current Ganglia metrics implementation is incompatible with Ganglia 3.1
