> For jobs using the HFileTarget we have found that running a DistCp to handleOutputs at the conclusion of a job, when the source and destination are in different filesystems, provides a substantial performance benefit compared to a single-threaded data copy. This enhancement is similar to what was suggested in CRUNCH-660.
