> FS API: Add a high-performance vectored Read to FSDataInputStream API

>                 Key: HADOOP-11867
>                 URL: https://issues.apache.org/jira/browse/HADOOP-11867
>             Project: Hadoop Common
>          Issue Type: New Feature
>          Components: fs, fs/azure, fs/s3, hdfs-client
>    Affects Versions: 3.0.0
>            Reporter: Gopal Vijayaraghavan
>            Assignee: Owen O'Malley
>            Priority: Major

>          Time Spent: 3h 50m
>  Remaining Estimate: 0h
>
> The most significant way to read from a filesystem in an efficient way is to 
> let the FileSystem implementation handle the seek behaviour underneath the 
> API to be the most efficient as possible.
> A better approach to the seek problem is to provide a sequence of read 
> locations as part of a single call, while letting the system schedule/plan 
> the reads ahead of time.
> This is exceedingly useful for seek-heavy readers on HDFS, since this allows 
> for potentially optimizing away the seek-gaps within the FSDataInputStream 
> implementation.
> For seek+read systems with even more latency than locally-attached disks, 
> something like a {{readFully(long[] offsets, ByteBuffer[] chunks)}} would 
> take of the seeks internally while reading chunk.remaining() bytes into each 
> chunk (which may be {{slice()}}ed off a bigger buffer).
> The base implementation can stub in this as a sequence of seeks + read() into 
> ByteBuffers, without forcing each FS implementation to override this in any 
> way.
