	// references this video, but the provided code is different than video.

	// The video does a bunch of stuff to obtain and process the tweets, but
	// what "val texts = " becomes is simply an array of strings, so I just
	// made a text file with one log entry per line (I'm trying to classify logs)
	// and did something like:

	val texts = sc.textFile("input.log")
