Apache Spark reassigned SPARK-32921: ------------------------------------ Assignee: (was: Apache Spark) > Extend MapOutputTracker to support tracking and serving the metadata about > each merged shuffle partitions for a given shuffle in push-based shuffle > scenario > ------------------------------------------------------------------------------------------------------------------------------------------------------------ > > Key: SPARK-32921 > URL: https://issues.apache.org/jira/browse/SPARK-32921 > Project: Spark > Issue Type: Sub-task > Components: Shuffle, Spark Core > Affects Versions: 3.1.0 > Reporter: Min Shen > Priority: Major > > Similar to MapStatus, which tracks the metadata about each map task's shuffle > output, we also need to track the metadata about each merged shuffle > partition with push-based shuffle. We currently term this as MergeStatus. > Since MergeStatus tracks metadata from the perspective of reducer tasks, it's > not efficient to break up the metadata tracked in a MergeStatus and spread it > across multiple MapStatus. -- 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
