Thanks for reply, but I don't think metric exposed to Ganglia would be what i am really looking for..
what i am looking for is some kind of these (but not limit to) Job_xxxx_yyyy CPU time: 10204 sec. <--aggregate from all tasknodes IOPS: 2344 <-- aggregated from all datanode MEM: 30G <-- aggregated etc, Job_aaa_bbb CPU time: IOPS: MEM: Sorry for ambiguous question.
