Subject [jira] [Commented] (CRUNCH-212) Need target wrapper for HFileOuptutFormat
Date Wed, 31 Jul 2013 19:19:48 GMT


Gabriel Reid commented on CRUNCH-212:

Cool, just took it for a mini test-run in local mode and seems to be working great -- I'm
looking forward to trying this out on a bigger job.

One thing that would be interesting (already brought up on the dev list) would be to have
an integration test that runs the job in distributed mode so that writing files for multiple
regions can be included in the integration tests.

> 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?
