TisonKun opened a new pull request #9861: [FLINK-14237][yarn] No need to rename shipped Flink jar URL: https://github.com/apache/flink/pull/9861 ## What is the purpose of the change Currently, when we ship Flink jar configured by `-yj`, we always rename it as `flink.jar`. It seems a redundant operation since we can always use the exact name of the real jar. It also causes some confusion to our users who should not be required to know about Flink internal implementation that they configure a specific Flink jar(said `flink-private-suffix`.jar) but cannot find it on YARN container, because it is now `flink.jar`. ## Brief change log ship flink jar with its original name. ## Verifying this change This change is already covered by existing tests, such as: - YarnClusterDescriptorTest - UtilsTest ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive):(no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes, on YARN we now always ship flink jar with its original name) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature? (no) - If yes, how is the feature documented? (not applicable)
