Todd Lipcon commented on HDFS-3246:
-----------------------------------

Agreed -- this would be particularly useful for HBase which does a lot of preads

> There is no pread equivalent in ByteBufferReadable. We should consider adding one. It would be relatively easy to implement for the distributed case (certainly compared to HDFS-2834), since DFSInputStream does most of the heavy lifting.
