Hello

I wrote example of "Monitoring the Wikipedia Edit Stream" in Intellij Idea,
but I got errors on "acc.f0 , acc.f1" which was like this:

Error:(39, 28) java: cannot find symbol
  symbol:   variable f0
  location: variable acc of type
scala.Tuple2<java.lang.String,java.lang.Long>

Would you please tell me how to solve this problem?

Thank you in advance.
