Re: Hadoop 0.19.2 and Ganglia 3.1.3

The apache dist.
I can't use the cloudera one because of a current requirement on Nutch 1.0. But I have seen talk that nutch is being migrated to 0.20 or 0.21

hi john

what dist are you using?
apache dist or cloudera dist?

if the apache dist ，you must patch it by yourself
until apache 0.20.1 dist the gangla31 has not included yet.

if  the cloudera 0.20.1+152 it has all done for you

I switched to GangliaContext31 and it threw Class not found  
exceptions.


Any ideas?

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,
