So, I'm not sure if I'm reading this correctly, but is this thread stating that Ganglia doesn't support IPV6? The Ganglia site claims to support it.
I'm running HDP 1.3.2 on CentOS 6.4 and I'm receiving the "There was no data available. Possible reasons include inaccessible Ganglia service."
I have IPV4 enabled as well and I've tried Javier's solution with no success, so, what else could cause this?
