Andrew Or updated SPARK-8119: ----------------------------- Summary: HeartbeatReceiver should not call sc.killExecutor (was: Spark will set total executor when some executors fail.) > HeartbeatReceiver should not call sc.killExecutor > ------------------------------------------------- > > Key: SPARK-8119 > URL: https://issues.apache.org/jira/browse/SPARK-8119 > Project: Spark > Issue Type: Bug > Components: Scheduler > Affects Versions: 1.4.0 > Reporter: SaintBacchus > > DynamicAllocation will set the total executor to a little number when it > wants to kill some executors. > But in no-DynamicAllocation scenario, Spark will also set the total executor. > So it will cause such problem: sometimes an executor fails down, there is no > more executor which will be pull up by spark. > === EDIT by andrewor14 === > The issue is that the AM forgets about the original number of executors it > wants after calling sc.killExecutor. Even if dynamic allocation is not > enabled, this is still possible because of heartbeat timeouts. > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
