Mridul Muralidharan reassigned SPARK-32919: ------------------------------------------- Assignee: Venkata krishnan Sowrirajan > Add support in Spark driver to coordinate the shuffle map stage in push-based > shuffle by selecting external shuffle services for merging shuffle partitions > ----------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: SPARK-32919 > URL: https://issues.apache.org/jira/browse/SPARK-32919 > Project: Spark > Issue Type: Sub-task > Components: Shuffle, Spark Core > Affects Versions: 3.1.0 > Reporter: Min Shen > Assignee: Venkata krishnan Sowrirajan > Priority: Major > Fix For: 3.1.0 > > > In the beginning of a shuffle map stage, driver needs to select external > shuffle services as the mergers of the shuffle partitions for the > corresponding shuffle. > We currently leverage the immediate available information about current and > past executor location information for this selection purpose. Ideally, this > would be behind a pluggable interface so that we can potentially leverage > information tracked outside of a Spark application for better load balancing > or for a disaggregate deployment environment. -- 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
