Zhu Zhu updated FLINK-22945: ---------------------------- Comment: was deleted (was: I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help the community manage its development. I see this issues has been marked as Critical but is unassigned and neither itself nor its Sub-Tasks have been updated for 7 days. I have gone ahead and marked it "stale-critical". If this ticket is critical, please either assign yourself or give an update. Afterwards, please remove the label or in 7 days the issue will be deprioritized. ) > StackOverflowException can happen when a large scale job is CANCELING/FAILING > ----------------------------------------------------------------------------- > > Key: FLINK-22945 > URL: https://issues.apache.org/jira/browse/FLINK-22945 > Project: Flink > Issue Type: Bug > Components: Runtime / Coordination > Affects Versions: 1.13.1, 1.12.4 > Reporter: Zhu Zhu > Assignee: Gen Luo > Priority: Critical > Labels: pull-request-available > Fix For: 1.14.0, 1.13.2 > > > The pending requests in ExecutionSlotAllocator are not cleared when a job > transitions to CANCELING or FAILING, while all vertices will be canceled and > assigned slot will be returned. The returned slot is possible to be used to > fulfill the pending request of a CANCELED vertex and the assignment will fail > immediately and the slot will be returned and used to fulfilled another > vertex in a recursive way. StackOverflow can happen in this way when there > are many vertices, and fatal error can happen and lead to JM will crash. A > sample call stack is attached below. > To fix this problem, we should clear the pending requests in > ExecutionSlotAllocator when a job is CANCELING or FAILING. Besides that, I > think it's better to also improve the call stack of slot assignment to avoid > similar StackOverflowException to occur. > ... > at >
