Steve Loughran commented on HADOOP-14603:
-----------------------------------------
For anyone expecting this: it's not on my todo list, so find someone else and
implement & submit yourself. As well as the usual s3 test policy, this is going
to need
* addition to filesystem.md to cover the input stream methods
* abstract contract test of them and implementations for those filesystems
which implement the API
* StreamCapabilities implementations in the streams to declare their support,
making it easier for callers to dynamically check.
> S3A input stream to support ByteBufferReadable

> Key: HADOOP-14603
> URL: https://issues.apache.org/jira/browse/HADOOP-14603
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3, test
> Affects Versions: 2.8.1
> Reporter: Steve Loughran
> Priority: Minor
>
> 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
