Subject [jira] [Commented] (CRUNCH-212) Need target wrapper for HFileOuptutFormat
Date Sat, 08 Jun 2013 15:27:20 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13678750#comment-13678750

Josh Wills commented on CRUNCH-212:
-----------------------------------

My understanding was that the HFileOutputFormat required a totally sorted set of inputs to
work properly, and so we never had it before b/c we didn't have that feature until 0.6. Is
that correct, [~gabriel.reid]?

> 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?
