Steve Loughran created HADOOP-19131:
---------------------------------------
Summary: Assist reflection iO with WrappedOperations class
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
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.
