Wenchen Fan resolved SPARK-21506. --------------------------------- Resolution: Fixed Fix Version/s: 2.3.0 Issue resolved by pull request 18711 [https://github.com/apache/spark/pull/18711] > The description of "spark.executor.cores" may be not correct > ------------------------------------------------------------- > > Key: SPARK-21506 > URL: https://issues.apache.org/jira/browse/SPARK-21506 > Project: Spark > Issue Type: Improvement > Components: Documentation > Affects Versions: 2.2.0 > Reporter: liuxian > Priority: Trivial > Fix For: 2.3.0 > > > The description for "spark.executor.cores" :"The number of cores assigned to > each executor is configurable. When this is not explicitly set, only one > executor per application will run the same worker " > I think it is not correct, because if one application is not assigned > enough cores in the first `schedule()`, another executor may be launched on > the same worker in the next time. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
