[jira] Created: (HBASE-3472) New import/export jobs based on HFiles

New import/export jobs based on HFiles
--------------------------------------

                 Key: HBASE-3472
                 URL: https://issues.apache.org/jira/browse/HBASE-3472
             Project: HBase
          Issue Type: New Feature
    Affects Versions: 0.92.0
            Reporter: Todd Lipcon
             Fix For: 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!
