Elliott Clark resolved HBASE-3472.
----------------------------------
    Resolution: Not a Problem

Copy Table now provides this with the ability to use HFileV2's.

>                 URL: https://issues.apache.org/jira/browse/HBASE-3472
>             Project: HBase
>          Issue Type: New Feature
>    Affects Versions: 0.92.0

> Not sure if I'll have time to work on this, but the old sequencefile-based import/export
are not as efficient as one based on HFiles would be. Idea is:
> - hbase exporthf: TableInputFormat -> Identity -> HFileOutputFormat   (should also
take time ranges, etc, for incremental backup)
> - hbase importhf: perhaps this is just an improvement to the existing completeBulkLoad
that does parallel splitting when the input HFiles don't "fit" the target regions (right now
this is single-threaded)
> This would be a good project for a new contributor!
