EronWright opened a new pull request #7389: [FLINK-11237] [table] Enhance LocalExecutor to wrap TableEnvironment w/ classloader URL: https://github.com/apache/flink/pull/7389 ## What is the purpose of the change The `LocalExecutor` calls into the table environment to execute queries, explain statements, and much more. Any call that involves resolving a descriptor to a factory implementation must be wrapped in the context classloader. Some of the calls already are wrapped (for resolving UDFs). With new functionality coming for resolving external catalogs with a descriptor (FLINK-9172), other call sites must be wrapped. This PR wraps all calls from local executor to table environment, for consistency. Seems wise to give the table environment maximum flexibility. ## Brief change log - use the context classloader for all interactions with TableEnvironment _Note: based on PR #7388; please ignore changes outside of `LocalExecutor` and `ExecutionContext`._ ## Verifying this change This change is already covered by existing tests, such as `DeploymentTest`, which exercises the `LocalExecutor`'s classloading. Note that a subsequent PR will enhance `DeploymentTest` for more coverage (FLINK-9172). ## 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? no - If yes, how is the feature documented?
