Olga Natkovich commented on MAPREDUCE-220:
------------------------------------------
It would be very useful for profiling purposes if applications could get
resource utilization information via counters. Either detailed information for
each map/reduce or min/max/average could be useful.
- Average CPU utilization
- Max memory usage
- Average inbound and outbound I/0. (Not sure if it is possible to obtain this
information on per process basis.)
