----------------------------

    Attachment: crunch-212-v1.patch

update patch to fix issues mentioned by Gabriel and Micah:
- use mini MR cluster to test with multiple regions (which is much slower than LocalJobRunner)
- comment a small paragraph to justify the use of HFileOutputFormatForCrunch
- remove the duplicate call of getDefaultWorkFile

> I need to import data to hbase from MR. I found HFileOutputFormat is ~5x more efficient
than HTableOutputFormat. So maybe we need a target wrapper for it.
> Future more, is it possible to call HBase to load it automatically after HFiles are generated?
