Hi,
I have a RDD of key-value pairs. Now I want to find the key for which the
values has the largest number of elements. How should I do that?
Basically I want to select the key for which the number of items in values
is the largest.
Thank You
If you mean your values are all a Seq or similar already, then you just
take the top 1 ordered by the size of the value:
rdd.top(1)(Ordering.by(_._2.size))
