backport to 4.3 Fixed an issue where group.consumer.assignors did not check for assignor name collisions. Previously, configuring duplicate assignors (such as using both a short name and a fully qualified class name) or using a custom assignor with a built-in name passed startup validation, but caused runtime crashes later during group coordinator loading. Key Changes: Added broker-side duplicate name validation that throws ConfigException at startup if two entries resolve to the same name. Prevented custom assignors from reusing reserved built-in names (e.g., uniform, range). Preserved support for configuring built-in assignors via their fully qualified class names. Added corresponding unit tests in GroupCoordinatorConfigTest and verified existing integration tests. -- This is an automated message from the Apache Git Service.
