------------------------------------------

Hi [~bharatviswa] thanks for the patch.
I want to clarify one thing: block size is preserved if -p options are not specified. However,
if -p options are specified, block size is preserved only if -pb is specified. So it's not
always enabled. Does that make sense to you?

> HADOOP-8143 is an incompatible change. I think it deserves an update in the distcp doc.
