Amareshwari Sriramadasu commented on MAPREDUCE-1635:
----------------------------------------------------
bq. MapOutputFile is still being used in TaskTracker process space, as a member
of TaskRunner class.
I raised MAPREDUCE-1662 for this.
bq. getRunState() != TaskStatus.State.SUCCEEDED check is removed in
calculateOutputSize(). I guess we need this check if some other caller also
calls this method
This check is not needed because calaculateOutputSize is called from done(). If
any other caller calls it, it will return -1 because the file is not there. We
cannot add the check, since SUCCEEDED state is not set by Task, it is set by
TaskTracker whenever the Task reports done().

> 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.
