Matei Zaharia created SPARK-10008: ------------------------------------- Summary: Shuffle locality can take precedence over narrow dependencies for RDDs with both Key: SPARK-10008 URL: https://issues.apache.org/jira/browse/SPARK-10008 Project: Spark Issue Type: Bug Components: Scheduler Reporter: Matei Zaharia
The shuffle locality patch made the DAGScheduler aware of shuffle data, but for RDDs that have both narrow and shuffle dependencies, it can cause them to place tasks based on the shuffle dependency instead of the narrow one. This case is common in iterative join-based algorithms like PageRank and ALS, where one RDD is hash-partitioned and one isn't. -- 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
