Description

Looking at the job counters page on the history server for a finished job, it shows 3 columns for each counter - map, reduce, total. The total appears correct, but map and reduce columns are always zero. If you click on a particular column it does show you the map/reduce task and the value of each one.

Going to attach screenshots shortly.
