Apache Spark reassigned SPARK-10008: ------------------------------------ Assignee: (was: Apache Spark) > 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
