Robert Joseph Evans commented on MAPREDUCE-3988:
------------------------------------------------
Looking at the patch I think it looks good to me, but I would like Vinod's
opinion on it before checking it in, because the last time I jumped the gun and
that is why we need this patch.
> mapreduce.job.local.dir doesn't point to a single directory on a node.

> After MAPREDUCE-3975, mapreduce.job.local.dir is set correctly for the tasks
> but it doesn't point to the same directory for all tasks running on the node.
> It is a public API. Either we should point to a single directory or point it
> to all directories and change the documentation to say that it points to all
> dirs.
