Apache Spark commented on SPARK-4214: ------------------------------------- User 'sryza' has created a pull request for this issue: https://github.com/apache/spark/pull/3204 > With dynamic allocation, avoid outstanding requests for more executors than > pending tasks need > ---------------------------------------------------------------------------------------------- > > Key: SPARK-4214 > URL: https://issues.apache.org/jira/browse/SPARK-4214 > Project: Spark > Issue Type: Improvement > Components: Spark Core, YARN > Affects Versions: 1.2.0 > Reporter: Sandy Ryza > Assignee: Sandy Ryza > > Dynamic allocation tries to allocate more executors while we have pending > tasks remaining. Our current policy can end up with more outstanding > executor requests than needed to fulfill all the pending tasks. Capping the > executor requests to the number of cores needed to fulfill all pending tasks > would make dynamic allocation behavior less sensitive to settings for > maxExecutors. -- 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
