Brian Bockelman updated HADOOP-4675:
------------------------------------
Attachment: HADOOP-4675-v6.patch
Hm - found a bug in the v5 patch. This next one currently uses the DNS class
correctly as Steve suggested.
This next one includes a test case for Ganglia -- it's quite simple. All it
does is configure the MiniDFSCluster to report to Ganglia31, and then starts up
a separate thread which listens for metrics. It verifies that the hostname is
properly set inside the packet sent to Ganglia, but does not verify that all
the formatting is correct.
This appears to be the first test for Ganglia? Probably should have written it
awhile ago.
> Current Ganglia metrics implementation is incompatible with Ganglia 3.1
