Subject [jira] [Commented] (HBASE-10642) Add M/R over snapshots to 0.94
Date Mon, 10 Mar 2014 00:52:42 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13925371#comment-13925371

Lars Hofhansl commented on HBASE-10642:
---------------------------------------

I realize now that the block distribution part of the trunk patch is important, this patch
misses that.
I'll add that as well as the scan metrics.
Tried to just backport the trunk patch, but it's too invasive for 0.94.

> I think we want drive towards all (or most) M/R over HBase to be against snapshots and
HDFS directly.
> Adopting a simple input format (even if just as a sample) as part of HBase will allow
us to direct users this way.
