Copying Data from HDP-2.x to HDP-1.x Clusters

Copying Data from HDP-1.x to HDP-2.x Clusters is also supported, however, HDP-1.x is not aware of a new checksum introduced in HDP-2.x.

To copy data from HDP-2.x to HDP-1.x: Skip the checksum check during source 2.x --> 1.x.


Ensure that the file to be copied is in CRC32 before distcp 2.x --> 1.x.
