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

Any ideas?

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

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,
