int num = 0;
for(int i = 0; i < length(number); i++) {
num *= 10;
num += number.charAt(i) - '0';
println("i :" + num);
}
Why do we subtract '0' at the end?

If you use plain spark you can join two RDDs. let a = RDD<Tuple2<K,T>> let b = RDD<Tuple2<K,S>> RDD<Tuple2<K,Tuple2<S,T>>> c = a.join(b) This produces an RDD of every pair for key K. There are also leftOuterJoin, rightOuterJoin, and fullOuterJoin methods on RDD. So you have to map both datasets to...

You should not let BehaviourItem implement Comparable as it doesn’t have a natural order. Instead, implement different Comparators for the different properties. Note that in Java 8, you can implement such a Comparator simply as Comparator<BehaviourItem> orderBySpeed=Comparator.comparingInt(BehaviourItem::getSpeed); which is the equivalent of Comparator<BehaviourItem> orderBySpeed=new Comparator<BehaviourItem>() { public int compare(BehaviourItem a, BehaviourItem...
