> WrappedIO to export modern filesystem/statistics APIs in a reflection

> Key: HADOOP-19131
> URL: https://issues.apache.org/jira/browse/HADOOP-19131
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs, fs/azure, fs/s3
> Affects Versions: 3.4.0, 3.3.6
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
>
> parquet, avro etc are still stuck building with older hadoop releases.
> This makes using new APIs hard (PARQUET-2171) and means that APIs which are 5
> years old such as HADOOP-15229 just aren't picked up.
> This lack of openFIle() adoption hurts working with files in cloud storage as
> * extra HEAD requests are made
> * read policies can't be explicitly set
> * split start/end can't be passed down
> HADOOP-18679 added a new WrappedIO class.
> This jira proposes extending this with
> * more of the filesystem/input stream methods
> * iOStatistics
> * Pull in parquet DynMethods to dynamially wrap and invoke through tests.
> This class, DynamicWrappedIO is intended to be copied into libraries
> (parquet, iceberg) for their own use.
> * existing tests to use the dynamic binding for end-to-end testing.
> +then get into the downstream libraries and use where appropriate
