Saisai Shao created SPARK-9468: ---------------------------------- Summary: Avoid scheduling tasks on preemption executors Key: SPARK-9468 URL: https://issues.apache.org/jira/browse/SPARK-9468 Project: Spark Issue Type: Improvement Components: Spark Core, YARN Reporter: Saisai Shao Priority: Minor
Currently Spark SchedulerBackend has no mechanism to be notified of preemption of executors by cluster manager, this will make SchedulerBackend keep scheduling tasks on the to-be-preempted executors and finally be failed. Also this cumulative failure will possibly lead to job failure. So Spark SchedulerBackend should be notified and avoid scheduling tasks on preemption nodes to avoid unnecessary failure. -- 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
