Ivan Mitic commented on MAPREDUCE-4321:
---------------------------------------
Thanks Daryn!
bq. One suggestion to maybe consider, would it in general help to create a
Path#toFile() and Path(File) ctor? I had consider the additional ctor change on
HADOOP-8139 and I believe Doug liked the idea.
I also like the idea. Although, one can argue, instead of doing these
conversions, why not just use File or Path across the board in that scenario
(RawLocalFileSystem aside). What do you think about doing this in a separate
Jira so that we can easily pull it out if needed?
