> Currently, HBase supports the pushing of multiple scans to mapreduce jobs
> over live tables (via MultiTableInputFormat) but only supports a single scan
> for mapreduce jobs over table snapshots. It would be handy to support
> multiple scans over snapshots as well, probably through another input format
> (MultiTableSnapshotInputFormat?). To mimic the functionality present in
> MultiTableInputFormat, the new input format would likely have to take in the
> names of all snapshots used in addition to the scans.
