Steve Loughran commented on HADOOP-14603:
-----------------------------------------

i think we should do this and the basic read(bytebuffer)/readFUlly as parquet 
currently uses it a lot and we get better info on read range if any reading 
into temp buffers is done in the cloud connector

> S3A input stream to support ByteBufferReadable

>    Affects Versions: 2.8.1

> S3AInputStream could support {{ByteBufferReadable, 
> HasEnhancedByteBufferAccess}} and the operations to read into byte buffers.
> This is only if we can see a clear performance benefit from doing this or the 
> API is being more broadly used
