> distcp writes out a SequenceFile containing the source files to transfer, and
> their sizes. Map tasks are created over spans of this file, representing
> files which each mapper should transfer. In practice, some transfer loads
> yield many empty map tasks and a few tasks perform the bulk of the work.
