--------------------------------------
> 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
> Priority: Major
>
> 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!
