> PyFlink apache-flink package is missing the NOTICE file
> -------------------------------------------------------
>
>                 Key: FLINK-41467
>                 URL: https://issues.apache.org/jira/browse/FLINK-41467

>            Reporter: Rui Fan
>            Assignee: Rui Fan
>            Priority: Blocker
>              Labels: pull-request-available

>
> The {{apache-flink}} Python package published to PyPI (both the sdist and the 
> wheels) has not contained a NOTICE file since 1.13.0.
> {{flink-python/MANIFEST.in}} contains {{include NOTICE}}, but there is no 
> {{flink-python/NOTICE}} file and {{flink-python/setup.py}} only copies the 
> root LICENSE into the package. The logic that generated a NOTICE file for 
> this package was removed together with the bundled licenses in FLINK-22095, 
> so {{include NOTICE}} silently matches nothing. The 
> {{apache-flink-libraries}} package is not affected, its setup.py still 
> generates a NOTICE file.
> The ASF release policy requires every distributed package to ship a NOTICE 
> file:
> * https://www.apache.org/legal/release-policy.html#licensing-documentation : 
> "Each package MUST provide a LICENSE file and a NOTICE file which account for 
> the package's exact content."
> * https://infra.apache.org/licensing-howto.html : a NOTICE file containing 
> the standard ASF attribution is required even for packages that only contain 
> ASF code.
> The {{apache-flink}} package only contains Apache Flink code (the pyflink 
> Python sources plus the bin/conf scripts from flink-dist), so the fix is to 
> add a {{flink-python/NOTICE}} file with the standard ASF attribution (same 
> header as the root NOTICE):
> {noformat}
> Apache Flink
> Copyright 2014-2026 The Apache Software Foundation
> This product includes software developed at
> The Apache Software Foundation (http://www.apache.org/).
> {noformat}
> The root NOTICE must not be copied as is, because it lists third-party 
> material that is not bundled in the Python package.
