Description
When Hadoop reports Datanode information to JMX, the bean uses the name "DataNode-" + storageid. The storage ID incorporates a random number and is unpredictable.
This prevents me from monitoring DFS datanodes through Hadoop using the JMX interface; in order to do that, you must be able to specify the bean name on the command line.
The fix is simple, patch will be coming momentarily. However, there was probably a reason for making the datanodes all unique names which I'm unaware of, so it'd be nice to hear from the metrics maintainer.
