Siddharth Seth updated MAPREDUCE-4582:
--------------------------------------
Priority: Minor (was: Major)
Target Version/s: MR-3902
Summary: [MAPREDUCE-3902] ScheduledRequests#remove should remove
the elements from mapsHostMapping and mapsRackMapping (was:
ScheduledRequests#remove should remove the elements from mapsHostMapping and
mapsRackMapping)
Tsuyoshi, the removal would be a little more efficient by using
attemptToLaunchRequestMap. That contains a list of hosts / racks for an
attemptId. It's also not required for reduce attempts.
assignToMap was originally written to take care of stale entries in these maps.
