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!
