[GitHub] [flink] zhuzhurk opened a new pull request #16842: [FLINK-23806][runtime] Avoid StackOverflowException when a large scale job failed to acquire enough slots in time
zhuzhurk opened a new pull request #16842:
URL: https://github.com/apache/flink/pull/16842
## What is the purpose of the change
This fix is to avoid StackOverflowException which will lead to JM crash.
When requested slots are not fulfilled in time, task failure will be triggered and all related tasks will be canceled and restarted. However, in this process, if a task is already assigned a slot, the slot will be returned to the slot pool and it will be immediately used to fulfill pending slot requests of the tasks which will soon be canceled. The execution version of those tasks are already bumped in DefaultScheduler#restartTasksWithDelay(...) so that the assignment will fail immediately and the slot will be returned to the slot pool and again used to fulfill pending slot requests. StackOverflow can happen in this way when there are many vertices, and fatal error can happen and lead to JM crash.
To fix the problem, this PR will cancel the pending requests of all the tasks which will be canceled soon(i.e. tasks with version bumped) before canceling these tasks.
## Verifying this change

- *Added unit test DefaultSchedulerTest#pendingSlotRequestsOfVerticesToRestartWillNotBeFulfilledByReturnedSlots*
