Andreas created SPARK-9746: ------------------------------ Summary: PairRDDFunctions.countByKey: values/counts always 1 Key: SPARK-9746 URL: https://issues.apache.org/jira/browse/SPARK-9746 Project: Spark Issue Type: Bug Components: Spark Core Affects Versions: 1.4.0 Reporter: Andreas
org.apache.spark.rdd.PairRDDFunctionscountByKey(): Map[K, Long] = self.withScope { self.mapValues(_ => 1L).reduceByKey(_ + _).collect().toMap } obviously always returns count 1 for each key. If I understand the docs correctly I would expect this implementation: self.mapValues(_.size).reduceByKey(_ + _).collect().toMap -- 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
