## What is the purpose of the change YARN e2e tests are using a roughly 7 years old KDC docker image which is hard to maintain. In this PR I've created a `Dockerfile` to build KDC on-the-fly. ## Brief change log * Restructured the docker-compose part (now it's possible to use `docker-compose build`) * Added `kdc/Dockerfile` to build it locally * Moved the original docker files/configs into hadoop directory * Made `hadoop/Dockerfile` hadoop version agnostic * Modified `README.md` for the docker images to reflect actual stand ## Verifying this change Existing YARN e2e tests. ## 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, Kubernetes/Yarn, ZooKeeper:no - 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 -- This is an automated message from the Apache Git Service.
