Todd Lipcon commented on MAPREDUCE-6067:
----------------------------------------
I checked this on a cluster and it did fix the "spilled records" counter. But
it seems like some other map counters are still missing:
{code}
Map output bytes 0 0 0
Map output materialized bytes 0 0 0
Map output records 0 0 0
{code}
(fwiw I am running with MAPREDUCE-6055 in my local branch, so it's possible
that something there broke stuff)
> native-task: spilled records counter is incorrect

> After running a terasort, I see the spilled records counter at 5028651606,
> which is about half what I expected to see. Using the non-native collector I
> see the expected count of 10000000000. It seems the correct number of records
> were indeed spilled, because the job's output record count is correct.
