Sean Owen resolved SPARK-1247. ------------------------------ Resolution: Not a Problem Yes, this already works on {{RDD[Int]}} for example via implicits, which existed since 0.9 at least: {code} scala> val ints = sc.parallelize(Array(1,2,3)) ints: org.apache.spark.rdd.RDD[Int] = ParallelCollectionRDD[0] at parallelize at <console>:21 scala> ints.mean ... 2.0 {code} I think it may be prohibitive to specialize all this in Java, but, an RDD can easily be manually mapped to {{Double}}s in Java. > Support some of the RDD double functions on float and int as well. > ------------------------------------------------------------------ > > Key: SPARK-1247 > URL: https://issues.apache.org/jira/browse/SPARK-1247 > Project: Spark > Issue Type: New Feature > Components: Documentation, Java API, PySpark, Spark Core > Affects Versions: 1.0.0 > Reporter: prashant > Assignee: prashant > Priority: Minor > > Pyspark is already agnostic, but currently Java and scala provides the > implicit functions like stats/ histogram etc only if the RDD is on Double. > This can be extended easily to support more numeric types. -- 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
