Jerry He commented on HBASE-16672:

Also there is another place that needs to be taken care of, in the 
SecureBulkLoadListener where we move or copy the files to staging dir.  In the 
secure bulk load case, that is the place to decide copy or rename.

> Add option for bulk load to copy hfile(s) instead of renaming

> The cause was that the bulk loaded hfiles in source table were renamed during 
> bulk load step of incremental restore.
> To support incrementally restoring to multiple destinations, this issue adds 
> option which would always copy hfile(s) during bulk load.
