val data = "This is a good start, bingo!! bingo!!"
app.fromCollection(data.lines.toList).
// word => (word, count)
flatMap(line => line.split("[\\s]+")).map((_, 1)).
// (word, count1), (word, count2) => (word, count1 + count2)
groupBy(kv => kv._1).reduce(sum(_, _))

val appId = context.submit(app)
context.close()
