Review Comment:
   small parquet file,  src/test/parquet
   
   can we read the file ~10sKB
   does it just complete and not complete
   
   malformed footer

>          Components: fs/s3
>    Affects Versions: 3.4.2

> S3 recently released [Analytics Accelerator Library for Amazon 
> S3|https://github.com/awslabs/analytics-accelerator-s3] as an Alpha release, 
> which is an input stream, with an initial goal of improving performance for 
> Apache Spark workloads on Parquet datasets. 
> For example, it implements optimisations such as footer prefetching, and so 
> avoids the multiple GETS S3AInputStream currently makes for the footer bytes 
> and PageIndex structures.
> The library also tracks columns currently being read by a query using the 
> parquet metadata, and then prefetches these bytes when parquet files with the 
> same schema are opened. 
> This ticket tracks the work required for the basic initial integration. There 
> is still more work to be done, such as VectoredIO support etc, which we will 
> identify and follow up with.
