Aaron Kimball commented on MAPREDUCE-972:
-----------------------------------------
bq. Will such a short-term fix suffice until the long-term can be addressed
(0.22, probably)? If so, then there's perhaps no in point considering a more
complex interim solution.
Probably
bq. Should we associate this Jira issue with the short or long-term fix? If
long, then we might make it depend on a FileSystem API change, to support
progress callbacks.
Why not both?
