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)
CPU time: 10204 sec. <--aggregate from all tasknodes
IOPS: 2344 <-- aggregated from all datanode
MEM: 30G <-- aggregated
Sorry for ambiguous question.
