> HFileTarget should use DistCp when source and destination are in different

> Key: CRUNCH-675
> URL: https://issues.apache.org/jira/browse/CRUNCH-675
> Project: Crunch
> Issue Type: Improvement
> Reporter: Andrew Olson
> Priority: Major
>
> 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.
