Nigel Daley commented on HADOOP-481:
------------------------------------
FWIW, HADOOP-954 has changed all task related statistics to be per user (the
user that submitted the job). Currently, these counters are aggregated per
user:
map_input_bytes
map_input_records
map_output_bytes
map_output_records
shuffle_input_bytes
reduce_input_records
reduce_output_records
> Hadoop mapred metrics should include per job input/output statistics rather
> than per-task statistics

> Currently hadoop reports metrics such as input bytes, input records, etc on
> per-task basis. Accurate aggregation of these metrics is required at the
> job-level and reporting should be done on a per-job basis.
