I’m surprised B is even an option, it doesn’t count words correctly!

Wait, can you really use reduceByKey like that?

D looks wrong, flatmap should be flatMap.

Option D seems off to me; I don't recall using flatmap like that. I think it should be flatMap instead of flatmap.

I remember we did a similar question where we used flatMap and reduceByKey. I feel like option A might be incorrect because it uses reduce instead of reduceByKey.

I'm not entirely sure about option B; it seems like it might be counting the length of words instead of the number of words.

I think option C looks familiar; it uses reduceByKey, which we practiced in class for counting words.

I'm not entirely sure about this one. I'll need to think it through step-by-step to make sure I'm understanding the logic correctly. Maybe I'll jot down some notes before selecting an answer.

This seems straightforward. Option C is the clear winner - it's splitting the lines, mapping each word to a (word, 1) pair, and then reducing by key to get the final word counts.

I'm a bit confused by the syntax here. I'll need to review my notes on Spark streaming to make sure I understand how to properly use the flatMap, map, and reduceByKey functions.

Okay, I think I've got this. Option C looks like the right way to count the words on the stream. I'll go with that one.

Hmm, this looks like a tricky one. I'll need to carefully read through the options and think about the differences between them.

I definitely recall checking active calls being part of it, but I can't remember if it was all three actions we need to pick.

Is it just me, or does this question make it sound like Spark has a sense of humor? Option C is the one.

Haha, 'assuminglinesIs anDStreamobject' - that's a bit of a mouthful! Option C seems the most straightforward to me.

I disagree, I believe option C is the right choice as it correctly maps each word to a count and then reduces by key to get the total count.

I'm not sure about the difference between reduce and reduceByKey. Looks like option C is the way to go though.

Option C looks good to me. It splits the lines into words, maps each word to a (word, 1) pair, and then reduces by key to get the count of each word.
