> Continuing a discussion started in HDFS-2834, it would be slick to provide support for a true zero-copy read API. In this style API, rather than having the user pass buffers to read into, the DFS client would provide buffers to the user. This allows the client to pass slices of mmaped blocks, for example, which can cut one or two copies out of many read scenarios.
