rmetzger opened a new pull request #11983: URL: https://github.com/apache/flink/pull/11983
## What is the purpose of the change - Replace flink-shaded-hadoop dependencies by vanilla Hadoop dependencies Why? - in principle it is better for users to use exactly the same client-hadoop versions as the server components that they are running (instead of relying on some version we are packaging for them) - The flink-shaded-hadoop dependencies we are providing are known to have issues. The Flink community does not have the capacity to properly maintain them. The old Hadoop2 shaded dependencies are still compatible with Flink after this change. Open TODOs: - [ ] test on EMR 6, with Hadoop 3 - [ ] Update Flink documentation ## Verifying this change I verified this change on my personal CI: - https://dev.azure.com/rmetzger/Flink/_build/results?buildId=7940&view=results test (hadoop 2.4.1, hadoop 2.8.3 on JDK11, hadoop 3.1.3) all with e2e tests I tested the change on Google DataProc (Hadoop 2.9) ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (**yes** / no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (**yes** / no / don't know) ## Documentation - Does this pull request introduce a new feature? (yes / **no**) - If yes, how is the feature documented? (not applicable / **docs** / JavaDocs / not documented) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
