Sandy Ryza commented on SPARK-9808: ----------------------------------- Have we considered removing the hash-based shuffle entirely? Especially without shuffle file consolidation, it's almost always a poor choice. > Remove hash shuffle file consolidation > -------------------------------------- > > Key: SPARK-9808 > URL: https://issues.apache.org/jira/browse/SPARK-9808 > Project: Spark > Issue Type: Improvement > Components: Shuffle, Spark Core > Reporter: Josh Rosen > Assignee: Josh Rosen > > I think that we should remove {{spark.shuffle.consolidateFiles}} and its > associated implementation for Spark 1.5.0. This feature isn't properly tested > and does not work with the external shuffle service. Since it's likely to be > buggy and since its motivation has been subsumed by sort-based shuffle, I > think it's a prime candidate for removal now. -- 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
