             Summary: Async I/O API Example For Scala has Variable Name error
                 Key: FLINK-9317
                 URL: https://issues.apache.org/jira/browse/FLINK-9317
             Project: Flink
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.4.2, 1.4.1
            Reporter: Yazdan Shirvany


h2. Async I/O API Scala Example has duplicated {{resultFuture variable with different data type.}}

 

{{resultFuture: ResultFuture[(String, String)]}}

{{ val resultFuture: Future[String]}}

 

{{this cause error on compile as variables have same naming.}}

 

{{In order to example works properly we need to update variable names to be distinct,}}

 

{{```}}

override def asyncInvoke(input: (String,String, String), resultFuture: ResultFuture[(String,String, String, String)]): Unit = {


 // issue the asynchronous request, receive a future for the result
 val *resultFutureRequested*: Future[String] = Future {
 // client2.query(str)
 client.getAccountReferenceId(token, input._1)
 }

 // set the callback to be executed once the request by the client is complete
 // the callback simply forwards the result to the result future
 *resultFutureRequested*.onSuccess {
 case result: String => {
 resultFuture.complete(Iterable((input._1, input._2, input._3, result)))
 }
 }
}

{{```}}
