Description

The following counters are in milliseconds so "megabyte-seconds" might be better stated as "megabyte-milliseconds"
MB_MILLIS_MAPS.name= Total megabyte-seconds taken by all map tasks
MB_MILLIS_REDUCES.name= Total megabyte-seconds taken by all reduce tasks
VCORES_MILLIS_MAPS.name= Total vcore-seconds taken by all map tasks
VCORES_MILLIS_REDUCES.name= Total vcore-seconds taken by all reduce tasks
