> Optimize S3A recordReader policy for Random IO formats

> S3A filesystem client (inherited by Hadoop) supports the notion of input
> policies.
> These policies tune the behaviour of HTTP requests that are used for reading
> different filetypes such as TEXT or ORC.
> For formats such as ORC and Parquet that do a lot of seek operations, there
> is an optimized RANDOM mode that reads files only partially instead of fully
> (default).
> I am suggesting to add some extra logic as part of HiveInputFormat to make
> sure we optimize RecordReader requests for random IO when data is stored on
> S3A using formats such as ORC or Parquet.
