> The streaming version of WindowedWordCount example is broken on Dataflow.
> Currently, the injector cannot start up and emits the error
> "java.lang.RuntimeException: DataflowWorkerHarness should not be used for
> non-streaming pipelines". This in turn means that no messages are generated
> for the streaming pipeline to process.
> The problem is that DataflowExampleUtils uses a batch workflow to inject
> Google PubSub messages. This workflow reuses the real options and modifies
> them to be batch, setting isStreaming to false etc. However, with versioned
> containers, the option for workerHarnessContainerImage must now also be
> changed to use the batch image.
