Nick Dimiduk updated HIVE-6584:
-------------------------------
Attachment: HIVE-6584.10.patch
Updated the patch once more. This has been tested on a distributed cluster as
well, things are working correctly.
{noformat}
HADOOP_CLASSPATH=/path/to/high-scale-lib-1.1.1.jar hive -e "set
hive.hbase.snapshot.name=foo_snap; select count(*) from foo;"
{noformat}
Optionally you can specify {{hive.hbase.snapshot.restoredir}} to something
other than the default.
I also opened HBASE-11555 so we can do away with the reflection stuff after a
later release.

> HBASE-8369 provided mapreduce support for reading from HBase table snapsopts.
> This allows a MR job to consume a stable, read-only view of an HBase table
> directly off of HDFS. Bypassing the online region server API provides a nice
> performance boost for the full scan. HBASE-10642 is backporting that feature
> to 0.94/0.96 and also adding a {{mapred}} implementation. Once that's
> available, we should add an input format. A follow-on patch could work out
> how to integrate this functionality into the StorageHandler, similar to how
> HIVE-6473 integrates the HFileOutputFormat into existing table definitions.
