> 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.
