> ByteBufferReadable could help certain application performance, such as Impala. (See HDFS-14111)
> Additionally, if we support ByteBufferPositionedReadable, it would benefit HBase. (see HDFS-3246)
> Finally, we should add StreamCapabilities to let client probe for these abilities. (See HDFS-11644)
