Hi all,
How do I convert a DStream to a string ?
For instance, I want to be able to:
val myword = words.filter(word = word.startsWith(blah))
And use myword in other places, like tacking it onto (key, value) pairs,
like so:
val pairs = words.map(word = (myword+_+word, 1))
Thanks for any help,
What would it mean to make a DStream into a String? it's inherently a
sequence of things over time, each of which might be a string but
which are usually RDDs of things.

Hi Sean,
I'd just like to take the first word of every line, and use it as a
variable for later. Is there a way to do that?
Here's the gist of what I want to do:
val lines = KafkaUtils.createStream(ssc, localhost:2181, test,
Map(test - 10)).map(_._2)
val words = lines.flatMap(_.split( ))
Sure, that code looks like it does sort of what you describe but it's
mixed up in a few ways. It looks like you only want to operate on
words that start with SECRETWORD, but then you are prepending acct and
_ in the code but expecting something appending in the result. You
also seem like you want
