> Add common getFileBlockLocations() emulation for object stores, including S3A

> Components: fs/s3
> Affects Versions: 2.8.1
> Reporter: Steve Loughran

>
> It looks suspiciously like S3A isn't providing the partitioning data needed
> in {{listLocatedStatus}} and {{getFileBlockLocations()}} needed to break up a
> file by the blocksize. This will stop tools using the MRv1 APIS doing the
> partitioning properly if the input format isn't doing it own split logic.
> FileInputFormat in MRv2 is a bit more configurable about input split
> calculation & will split up large files. but otherwise, the partitioning is
> being done more by the default values of the executing engine, rather than
> any config data from the filesystem about what its "block size" is,
> NativeAzureFS does a better job; maybe that could be factored out to
> hadoop-common and reused?
