> 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.
