[jira] [Updated] (SPARK-42719) `ShuffledRowRdd#getPreferredLocations` should respect to `spark.shuffle.reduceLocality.enabled`
[ https://issues.apache.org/jira/browse/SPARK-42719?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
He Qi updated SPARK-42719:
--------------------------
Description:
Discuss as [https://github.com/apache/spark/pull/40307]
{{getPreferredLocations}} in {{ShuffledRowRDD}} should return {{Nil}} at the very beginning in case {{spark.shuffle.reduceLocality.enabled = false}} (conceptually).
This logic is pushed into MapOutputTracker though - and {{getPreferredLocationsForShuffle}} honors {{spark.shuffle.reduceLocality.enabled}} - but {{getMapLocation}} does not.
So the fix would be to fix {{getMapLocation}} to honor the parameter.
