Chao Shi commented on CRUNCH-212:
---------------------------------
I think I hit something Gabriel mentioned that does not map cleanly to the
crunch world:
HFileOutputFormat is not actually a target, as it needs a sort phase on rows as
well as a custom partitioner. So I have to make it a utility method:
HBaseBulkLoadUtils#save(String tableName, PCollection<Put or Delete>), which
does sort in an additional stage. It can also take advantage of handleOutputs()
to call HBase to load the generated HFiles.
Any better ideas?

> 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?
