Zhu Zhu created FLINK-15169: ------------------------------- Summary: Errors happen in the scheduling of DefaultScheduler is not shown in WebUI Key: FLINK-15169 URL: https://issues.apache.org/jira/browse/FLINK-15169 Project: Flink Issue Type: Bug Components: Runtime / Coordination Affects Versions: 1.10.0 Reporter: Zhu Zhu Fix For: 1.10.0
WebUI relies on {{ExecutionGraph#failureInfo}} and {{Execution#failureCause}} to generate error info (vis {{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). To solve it, 1. global failures should be recorded into {{ExecutionGraph#failureInfo}}, via {{ExecutionGraph#initFailureCause}} which can be exposed as {{SchedulerBase#initFailureCause}}. 2. for task failures, one solution I can think of is to avoid invoking {{DefaultScheduler#handleTaskFailure}} directly on scheduler's internal failures. Instead, we can introduce {{ExecutionVertexOperations#fail(ExecutionVertex)}} to hand the error to {{ExecutionVertex}} as a common failure. cc [~gjy] -- This message was sent by Atlassian Jira (v8.3.4#803005)
