zhuzhurk opened a new pull request #10541: [FLINK-15169][runtime] Set failures happen in DefaultScheduler to ExecutionGraph/Execution to make them visible to REST URL: https://github.com/apache/flink/pull/10541 ## What is the purpose of the change WebUI relies on ExecutionGraph#failureInfo and Execution#failureCause to generate error info (via JobExceptionsHandler#createJobExceptionsInfo). Errors happen in the scheduling of DefaultScheduler are not recorded into those fields, thus cannot be shown to users in WebUI (nor via REST queries). ## Brief change log - *set global failures to ExecutionGraph* - *set task deployment failures in DefaultScheduler to Execution via invoking Execution#markFailed* ## Verifying this change This change is verified by manually triggering glboal/task failures and checking the WebUI and REST. ## 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, 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?
