> 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.
