> It would be good to have a test mode in hive - this will help in checking the validity
of a hive drop on a production cluster.
> The following would be good to have:
> Testmode --> In testmode, all input tables are sampled (if not already sampled) and
all output tables are prefixed by a user supplied name.
> This way, multiple hive drops can be compared quickly for correctness
