Reynold Xin resolved SPARK-10710. --------------------------------- Resolution: Fixed Fix Version/s: 1.6.0 > Remove ability to set spark.shuffle.spill=false and > spark.sql.planner.externalSort=false > ---------------------------------------------------------------------------------------- > > Key: SPARK-10710 > URL: https://issues.apache.org/jira/browse/SPARK-10710 > Project: Spark > Issue Type: Sub-task > Components: Shuffle > Reporter: Josh Rosen > Assignee: Josh Rosen > Labels: releasenotes > Fix For: 1.6.0 > > > The {{spark.shuffle.spill=false}} configuration doesn't make much sense > nowadays: I think that this configuration was only added as an escape-hatch > to guard against bugs when spilling was first added. Similarly, setting > {{spark.sql.planner.externalSort=false}} doesn't make sense in newer > releases: many new implementations, such as Tungsten, completely ignore this > flag, so it's not applied in a consistent way. > In order to reduce complexity, I think that we should remove the ability to > disable spilling. Note that the {{tungsten-shuffle}} manager already does not > respect this setting, so removing this configuration is a blocker to being > able to unify the two sort-shuffle implementations. -- 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
