Saisai Shao commented on SPARK-5315: ------------------------------------ Yes, user can wrap with JavaDStream, but I think it is quite tricky and un-straightforward for users. Also from my understanding, change this API's signature is meaningful because the previous one is actually not correct. > reduceByWindow returns Scala DStream not JavaDStream > ---------------------------------------------------- > > Key: SPARK-5315 > URL: https://issues.apache.org/jira/browse/SPARK-5315 > Project: Spark > Issue Type: Bug > Components: Streaming > Affects Versions: 1.2.0 > Reporter: Saisai Shao > > {code} > def reduceByWindow( > reduceFunc: (T, T) => T, > windowDuration: Duration, > slideDuration: Duration > ): DStream[T] = { > dstream.reduceByWindow(reduceFunc, windowDuration, slideDuration) > } > {code} > It should return JavaDStream not DStream for java code. -- 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
