Chris Douglas commented on MAPREDUCE-972:
-----------------------------------------
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.
It's more of a use case/motivation for the FileSystem API changes. If DistCp
were ported to use new APIs supporting progress updates, then this would be
resolved as a side effect, right?
Can this be resolved as a documentation issue? A patch to the DistCp guide can
go into 0.21.

> rename() in S3 is implemented as copy + delete. The S3 copy operation can
> perform very slowly, which may cause task timeout.
