[error] [warn] /home/kou/work/oss/spark-scala-2.13/external/kafka-0-10/src/main/scala/org/apache/spark/streaming/kafka010/KafkaRDD.scala:251: method with a single empty parameter list overrides method without any parameter list                                                                
[error] [warn]   override def hasNext(): Boolean = requestOffset < part.untilOffset                                                               
[error] [warn]                                                                                                                                    
[error] [warn] /home/kou/work/oss/spark-scala-2.13/external/kafka-0-10/src/main/scala/org/apache/spark/streaming/kafka010/KafkaRDD.scala:294: method with a single empty parameter list overrides method without any parameter list                                                                
[error] [warn]   override def hasNext(): Boolean = okNext    

More specifically, what this PR fixes are

• Methods which has an empty parameter list and overrides an method which has no parameter list.

override def hasNext(): Boolean = okNext

• Methods which has no parameter list and overrides an method which has an empty parameter list.

      override def next: (Int, Double) = {

• Infix operator expression that the operator wraps.

    3L * math.min(k, numFeatures) * math.min(k, numFeatures)
    3L * math.min(k, numFeatures) * math.min(k, numFeatures) +
    + math.max(math.max(k, numFeatures), 4L * math.min(k, numFeatures)
      math.max(math.max(k, numFeatures), 4L * math.min(k, numFeatures) *
    * math.min(k, numFeatures) + 4L * math.min(k, numFeatures))

Why are the changes needed?

For building Spark with sbt and Scala 2.13.
