Hyukjin Kwon updated SPARK-9599: -------------------------------- Labels: bulk-closed (was: ) > Dynamic partitioning based on key-distribution > ---------------------------------------------- > > Key: SPARK-9599 > URL: https://issues.apache.org/jira/browse/SPARK-9599 > Project: Spark > Issue Type: Improvement > Components: Shuffle, Spark Core > Affects Versions: 1.4.1 > Reporter: Zoltán Zvara > Priority: Major > Labels: bulk-closed > > When - for example - using {{groupByKey}} operator with default > {{HashPartitioner}}, there might be a case when heavy keys get partitioned > into the same bucket, later raising an OOM error at the result partition. A > domain-based partitioner might not be able to help, when the outstanding > key-distribution changes from time to time (for example while dealing with > data streams). > Spark should identify these situations and change the partitioning > accordingly when a partitioning would raise an OOM later. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
