    Description

      This jira is intended for code sharing. I'd like to have a BlockSender which is resposible for reading a block from a disk and writing it to an output stream, and a BlockReceiver which receives a block from an input stream, writes it to a disk, and possibly writes it a mirror ouput stream to support pipeline writes. Block sender and receiver code is independent of any block IO protocols so it could be shared by block transfer, block write, block read, and future block replacement introduced by data node rebalancing.
