Description

This was found by cxorm via HDDS-2443.

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)
