      Description

      DFSClient with hedged reads enabled will often close previous spawned connections if it successfully reads from one of them. This can result in DataNode's BlockSender getting a socket exception and wrongly marking the block as suspect and to be rescanned for errors.

      This patch is aimed at adding windows specific network related exception messages to be ignored in BlockSender.sendPacket.
