> TableSnapshotInputFormat runs one map task per region in the table snapshot. This places
unnecessary restriction that the region layout of the original table needs to take the processing
resources available to MR job into consideration. Allowing to run multiple mappers per region
(assuming reasonably even key distribution) would be useful.
