Review comment:
Distcp supports running distributed copy for blocks of the same file in
parallel. Customers can use this option.
-blocksperchunk <blocksperchunk> | Number of blocks per chunk. When
specified, split files into chunks to copy in parallel | If set to a positive
value, files with more blocks than this value will be split into chunks of
<blocksperchunk> blocks to be transferred in parallel, and reassembled on the
destination. By default, <blocksperchunk> is 0 and the files will be
transmitted in their entirety without splitting. This switch is only applicable
when the source file system implements getBlockLocations method and the target
file system implements concat method.
