Subject Re: Hadoop Metrics Issue in ganglia.
Date Thu, 12 Sep 2013 18:55:12 GMT

Thanks for your reply.

@Chris - I haven't tried this on ganglia forums because I thought this
is something related to Hadoop. Though I'm able to see default metrics
from every nodes.

I'm not using any firewall, In addition my host entry looks like below. master master.bigmix.com loghost clone1 clone1.bigmix.com clone2 clone2.bigmix.com

I'm also able to lookup these machines through dns ( nslookup, host).

Did I missed something?
