Nick Dimiduk commented on HIVE-6584:
------------------------------------
Restore location is optional. It defaults to /tmp. The restore process creates
a uniquely named (random uuid) directory under this path for any give restore,
so users who never set this value will not conflict with each other.
It would be nice if hive had some kind of post-job hook that could be used to
clean up the restoredir artifacts after the input format is finished with them.

> 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.
