Sandy Ryza commented on MAPREDUCE-5006:
---------------------------------------
MAPREDUCE-4994 made it so that LocalClientProtocolProvider doesn't always set
the number of map tasks to 1. As 2 is the number in mapred-default, this means
that the local job runner now defaults to 2 mappers. Ideally, it would be set
to default to 1 and still be overridable via command line, but I am told this
isn't possible with the current way that configurations work. We could
possibly add in a mapred.local.job.maps?
