[jira] [Commented] (CRUNCH-212) Need target wrapper for HFileOuptutFormat

["Micah Whitacre (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CRUNCH-212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13725975#comment-13725975 ] 

Micah Whitacre commented on CRUNCH-212:
---------------------------------------

Haven't gotten to test out the patch but excited about the progress.  Do have a few comments:

* Should document justification in the HFileOutFormatForCrunch class on why we are using that over HFileOutputFormat.
* Lines 63 & 74 of the code you retrieve the exact same path. (Path path = getDefaultWorkFile(context, "");)

> 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?
