             Summary: abstract class Receiver should be explicit about the return type of its methods
                 Key: SPARK-14587
                 URL: https://issues.apache.org/jira/browse/SPARK-14587
             Project: Spark

          Components: Streaming
    Affects Versions: 2.0.0
            Reporter: Jacek Laskowski

The [org.apache.spark.streaming.receiver.Receiver|https://github.com/apache/spark/blob/master/streaming/src/main/scala/org/apache/spark/streaming/receiver/Receiver.scala#L102] abstract class defines API without specifying the return types explicitly, e.g.

{code}
def onStart()
def onStop()
...
{code}
