Key: MAPREDUCE-3699
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3699
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.0
Reporter: Vinod Kumar Vavilapalli
Fix For: 0.23.1
Mainly NM has a default of 5, RM has 10 and AM also has 10 irrespective of
num-slots, num-nodes and num-tasks respectively. Though ideally we want to
scale according to slots/nodes/tasks, for now increasing the defaults should be
enough.
