Error in import of flink-streaming-examples project [StockPrices.java]
Hello there,
I imported the flink-streaming-examples project [
https://github.com/mbalassi/flink/tree/stockprices/flink-staging/flink-streaming/flink-streaming-examples]
into eclipse but it shows me error in StockSource and TweetSource class
within StockPries.java.
I have attached the screenshot for more clarity.
When I point to the error symbol beside *StockSource* I get the following
message:
Multiple markers at this line
- The type StockPrices.StockSource must implement the inherited abstract
method
SourceFunction<StockPrices.StockPrice>.cancel()
- The type StockPrices.StockSource must implement the inherited abstract
method
SourceFunction<StockPrices.StockPrice>.run(SourceFunction.SourceContext<StockPrices.StockPrice>)
And for *reachEnd() *overriden method:
The method reachedEnd() of type StockPrices.StockSource must override or
implement a supertype method
Do I need to import some another project, attach as source to run the
StockPries.java.
Best Regards,
Subash Basnet

I think this example refers to a much older version (0.8) and is no longer
compatible
