dhruba borthakur commented on MAPREDUCE-220:
--------------------------------------------
I like the idea of sending this information via Counters.
This data could be used by schedulers to make decisions on what/when to
schedule new tasks or preempt existing tasks. For this use-case, it would be
nice if we can send them to the JT more frequently that 1 minute. any ideas
here?
