Dongjoon Hyun updated SPARK-24942: ---------------------------------- Target Version/s: 3.1.0 (was: 3.0.0) > Improve cluster resource management with jobs containing barrier stage > ---------------------------------------------------------------------- > > Key: SPARK-24942 > URL: https://issues.apache.org/jira/browse/SPARK-24942 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 3.0.0 > Reporter: Xingbo Jiang > Priority: Major > > https://github.com/apache/spark/pull/21758#discussion_r205652317 > We shall improve cluster resource management to address the following issues: > - With dynamic resource allocation enabled, it may happen that we acquire > some executors (but not enough to launch all the tasks in a barrier stage) > and later release them due to executor idle time expire, and then acquire > again. > - There can be deadlock with two concurrent applications. Each application > may acquire some resources, but not enough to launch all the tasks in a > barrier stage. And after hitting the idle timeout and releasing them, they > may acquire resources again, but just continually trade resources between > each other. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
