Chao Shi updated CRUNCH-212:
----------------------------
Attachment: crunch-212-v0.patch
Attached the final version.
This does not include the automatically bulk load code, but one can do it by
calling o.a.h.hbase.mapreduce.LoadIncrementalHFiles (as I did in test). This
patch uses its own version of HFileOutputFormat and does sort in MR shuffle
phase rather than reducer phase.
This is manually tested on a real cluster (hbase 0.94.0, multiple regions).
> Need target wrapper for HFileOuptutFormat

> 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?
