TEZ-4694 Add package-level Javadoc descriptions so generated API docs show a short summary for each package by lewismc · Pull Request #466 · apache/tez

lewismc · 2026-03-16T23:50:37Z

PR for TEZ-4694
Although this is a large PR is is fairly trivial.

Package-level Javadoc

Added short package descriptions to existing package-info.java files across tez-api, tez-common, tez-dag, tez-mapreduce, tez-runtime-library, and tez-javadoc-tools.
Introduced package-info.java for API packages that had none.

Javadoc

Fixed Javadoc warnings by escaping HTML in comments (e.g. &, <, <=) in tez-api, tez-runtime-library, and tez-mapreduce.

Build

Registered generated-sources (e.g. protobuf output) as compile source roots via build-helper-maven-plugin in tez-mapreduce, tez-runtime-library, tez-runtime-internals, and tez-dag.
Enabled forked compiler with increased memory for tez-mapreduce, tez-runtime-internals, and tez-dag to avoid missing .class file errors during test-compile.

Please check that the package visibility assignments are correct. Thank you for any review.

Regarding the test4tests -1 Vote I suppose we could add a plugin to Yetus which ensures a description exists for each package-info.java however I think this is overkill.
