wangfei created SPARK-4845: ------------------------------ Summary: Adding a parallelismRatio to control the partitions num of shuffledRDD Key: SPARK-4845 URL: https://issues.apache.org/jira/browse/SPARK-4845 Project: Spark Issue Type: Improvement Components: Spark Core Affects Versions: 1.1.0 Reporter: wangfei Fix For: 1.3.0
Adding parallelismRatio to control the partitions num of shuffledRDD, the rule is: Math.max(1, parallelismRatio * number of partitions of the largest upstream RDD) The ratio is 1.0 by default to make it compatible with the old version. When we have a good experience on it, we can change this. -- 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
