License failure is my fault and being addressed in #8112;
checkstyle is on an import

Can you fix that?
> S3A: Analytics accelerator for S3 to be enabled by default
> ----------------------------------------------------------
>
> Key: HADOOP-19559
> URL: https://issues.apache.org/jira/browse/HADOOP-19559
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs/s3
> Affects Versions: 3.5.0, 3.4.2
> Reporter: Ahmar Suhail
> Priority: Major
> Labels: pull-request-available
>
> Make "analytics" the default input stream in S3A.
> Goals
> * Parquet performance through applications running queries over the data
> (spark etc)
> * Performance for other formats good as/better than today. Examples: avro
> manifests in iceberg, ORC in hive/spark
> * Performance for other uses as good as today (whole-file/sequential reads of
> parquet data in distcp etc)
> * better resilience to bad uses (incomplete reads not retaining http streams,
> buffer allocations on long-retained data)
> * efficient on applications like Impala, which caches parquet footers itself,
> and uses unbuffer() to discard all stream-side resources. Maybe just throw
> alway all state on unbuffer() and stop trying to be sophisticated, or support
> some new openFile flag which can be used to disable footer parsing
