> 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. If the distcp could finish in an acceptable period then we don't need
> to wait for no diff. For example if 3 consecutive distcp jobs all finish
> within 10 minutes then we can predict the final distcp could also finish
> within 10 minutes. So we can start the final distcp directly.
