zjffdu opened a new pull request #8144: [FLINK-12159]. Enable YarnMiniCluster integration test under non-secure mode URL: https://github.com/apache/flink/pull/8144 ## What is the purpose of the change I can not run flink in YarnMiniCluster for integration test because yarn-site.xml is not shipped to yarn container (krb5Config must be non-empty otherwise yarn-site.xml won't been shipped). It doesn't make sense to to only allow yarn integration under secure mode. So this PR just try to enable YarnMiniCluster integration test under non-secure mode. I tested this PR for zeppelin flink integration test. ## Brief change log Straightforward code refactoring to separate `yarn-site.xml` and `krb5Config` file. ## Verifying this change *(Please pick either of the following options)* This change is a trivial rework / code cleanup without any test coverage. I verified this PR in zeppelin flink integration test. ## 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: (no ) - The S3 file system connector: (no ) ## Documentation - Does this pull request introduce a new feature?
