> We are trying to back a Hive Table by the Map Reduce over snapshots  and we don't want
to restore the snapshot to a restoreDir every time we want to execute a query. It would be
nice if there is boolean in the function 
> * TableSnapshotInputFormat.setInput * and exposed outside in the
> * TableMapReduceUtil.initTableSnapshotMapperJob *, with this boolean
> it will check whether the snapshot and the restore dir are in sync, rather than restoring
again. 
> Is this Idea looks Ok to you guys or you have any other suggestions, I will put up a
patch for this if this idea is ok for guys
