Tathagata Das commented on SPARK-4557: -------------------------------------- Wait is that with Java 7 or 8? Java 7 probably will be fine isnt it? But it does not make sense if it fails for Java 8. > Spark Streaming' foreachRDD method should accept a VoidFunction<...>, not a > Function<..., Void> > ----------------------------------------------------------------------------------------------- > > Key: SPARK-4557 > URL: https://issues.apache.org/jira/browse/SPARK-4557 > Project: Spark > Issue Type: Improvement > Components: Streaming > Affects Versions: 1.1.0 > Reporter: Alexis Seigneurin > Priority: Minor > Labels: starter > > In *Java*, using Spark Streaming's foreachRDD function is quite verbose. You > have to write: > {code:java} > .foreachRDD(items -> { > ...; > return null; > }); > {code} > Instead of: > {code:java} > .foreachRDD(items -> ...); > {code} > This is because the foreachRDD method accepts a Function<JavaRDD<...>, Void> > instead of a VoidFunction<JavaRDD<...>>. This would make sense to change it > to a VoidFunction as, in Spark's API, the foreach method already accepts a > VoidFunction. -- 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
