> Currently in the DistCpProcedure it must submit distcp round by round until
> there is no diff to go to the final distcp stage. The condition is very
> strict. During incremental copy stage, if the diff size is under the given
> threshold scope then we don't need to wait for no diff. We can start the
> final distcp directly.
