Can you elaborate more on how to reproduce the error? What's the maven archetype you use to generate the job, what's the flink version you used? what java version you used in Intellij?

I am suspecting either there's a mixed up on Scala / Java scaffold. Since your Tuple should be

org.apache.flink.api.java.tuple.Tuple2<...>

Also, please do not directly reply to one of the ongoing email thread as the discussion is pretty much unrelated.

Thanks,

Rong

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.
