> Key: HADOOP-19131
> URL: https://issues.apache.org/jira/browse/HADOOP-19131
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs, fs/azure, fs/s3
> Affects Versions: 3.4.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
>
> parquet, avro etc are still stuck building with older hadoop releases.
> This makes using new APIs hard (PARQUET-2117) 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
> Proposed
> # create class org.apache.hadoop.io.WrappedOperations
> # add methods to wrap the apis
> # test in contract tests via reflection loading -verifies we have done it
> properly.
