attilapiros commented on issue #24350: [SPARK-27348][Core] HeartbeatReceiver should remove lost executors from CoarseGrainedSchedulerBackend URL: https://github.com/apache/spark/pull/24350#issuecomment-482309869 Oh there must be a race condition as this test was running at my side locally, on the other hand your change contradicts https://issues.apache.org/jira/browse/SPARK-8119. > I think the problem is that sc.killExecutor is used incorrectly in HeartbeatReceiver. The intention of the method is to permanently adjust the number of executors the application will get. In HeartbeatReceiver, however, this is used as a best-effort mechanism to ensure that the timed out executor is dead.
