Piotr Nowojski commented on FLINK-17012: ---------------------------------------- [~chesnay] maybe after it makes sense to expose Task's state over the metrics? For monitoring purposes? Especially if we could also include completed (`FINISHED`/`FAILED`) states for some period of time after the completion in cases where failure of single Task doesn't restart whole job? > Expose stage of task initialization > ----------------------------------- > > Key: FLINK-17012 > URL: https://issues.apache.org/jira/browse/FLINK-17012 > Project: Flink > Issue Type: Improvement > Components: Runtime / Metrics, Runtime / Task > Reporter: Wenlong Lyu > Priority: Major > > Currently a task switches to running before fully initialized, does not take > state initialization and operator initialization(#open ) in to account, which > may take long time to finish. As a result, there would be a weird phenomenon > that all tasks are running but throughput is 0. > I think it could be good if we can expose the initialization stage of tasks. > What to you think? -- This message was sent by Atlassian Jira (v8.3.4#803005)
