Re: Hadoop 0.19.2 and Ganglia 3.1.3

So if I rollback to Ganglia 3.0.x does this problem go away, and everything should work?

Hey John,

You need the latest version of this patch for the 0.19.x branch:

http://issues.apache.org/jira/browse/HADOOP-4675
Sadly, the patch is quite aged and I haven't driven it to completion yet....

we use cloudera 0.20.1+152 dist. it has included the ganglia 3.1.x patch, 
maybe you could try it.

Has anybody else had any trouble running hadoop 0.19.2 and Ganglia 3.1.x?
I was surfing through the Jira/Google and it seems that there where some 
issues but have been resolved.

Any thoughts would be helpful.

Thank you,

-John
