Hairong Kuang updated MAPREDUCE-1981:
-------------------------------------
Attachment: mapredListFiles3.patch
Chris, thanks a lot for your review.
This patch fixed comments 1 & 3.
For comment 4, I decided to keep addInputPathRecursively. So listStatus
continues to use addInputPathRecursively instead of FileContext#listFiles. This
is for maintaining the old semantics to allow recursive listing to have an
option to be overridden.
> Improve getSplits performance by using listFiles, the new FileSystem API
