Find first element in RDD satisfying the given predicate

How to find the first element in a normal RDD( Because in PairRDD, we can use lookup(key) API ) which satisfy a predicate? And after finding the first element, it should exit the RDD traversal. Looking for a solution without using legacy for loops.

The above solutions stated are perfectly correct. Here is another method to achieve the same goal

How about

rdd.filter(p).top(1)

or if you don't have an order on the RDD

rdd.filter(p).take(1)
