Amareshwari Sriramadasu updated MAPREDUCE-1635:
-----------------------------------------------
Description:
MAPREDUCE-842 changed Child's mapred.local.dir to have attemptDir as the base
local directory. Also assumption is that
org.apache.hadoop.mapred.MapOutputFile always gets Child's mapred.local.dir.
But, MapOuptutFile.getOutputFile() is called from TaskTracker's conf, which
does not find the output file. Thus TaskTracker.tryToGetOutputSize() always
returns -1.
