Convert DStream to String

[Harold Nguyen]

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,

Harold
