> We are using the async I/O to make HTTP calls and one of the features we wanted to leverage was the retries, so we pulled the newest commit: [http://github.com/apache/flink/pull/19983] into our internal Flink fork.
> When I try calling the function {{AsyncDataStream.unorderedWaitWithRetry}} from the scala API I with a retry strategy from the java API I get an error as {{unorderedWaitWithRetry}} expects a scala retry strategy. The problem is that retry strategies were only implemented in java and not Scala in this PR: [http://github.com/apache/flink/pull/19983].
>  
> Here is some of the code to reproduce the error:
> {code:java}
> import org.apache.flink.streaming.api.scala.AsyncDataStream
> import org.apache.flink.streaming.util.retryable.{AsyncRetryStrategies => JAsyncRetryStrategies}
> val javaAsyncRetryStrategy = new JAsyncRetryStrategies.FixedDelayRetryStrategyBuilder[Int](3, 100L)
>     .build()
> val data = AsyncDataStream.unorderedWaitWithRetry(
>   source,
>   asyncOperator,
>   pipelineTimeoutInMs,
>   TimeUnit.MILLISECONDS,
>   javaAsyncRetryStrategy
> ){code}
