stack commented on HBASE-1684:

What should the contrib be called? 'backupmr'? How about dump? ExportMR and ImportMR should implement Tool. See the HStoreFileToStoreFile for sample. Then they can take command line arguments. Why have a map in ExportMR? It does nothing. Same for reducer? Just use Identity Map? For ImportMR, reduce does nothing either. Just don't have it in there and set reducer to zero in the job setup. Rather than a contrib, lets just add this to mapreduce package?
