--------------------------------------
Assignee: Zhu Shan
> JobClient.getAccumulators() blocks until streaming job has finished in local
> environment
> ----------------------------------------------------------------------------------------
>
> Key: FLINK-18685
> URL: https://issues.apache.org/jira/browse/FLINK-18685
> Project: Flink
> Issue Type: Bug
> Components: API / DataStream
> Affects Versions: 1.11.0
> Reporter: Robert Metzger
> Assignee: Zhu Shan
> Priority: Major
> Labels: starter
>
> *Steps to reproduce:*
> {code:java}
> JobClient client = env.executeAsync("Test");
> CompletableFuture<JobStatus> status = client.getJobStatus();
> LOG.info("status = " + status.get());
> CompletableFuture<Map<String, Object>> accumulators =
> client.getAccumulators(StreamingJob.class.getClassLoader());
> LOG.info("accus = " + accumulators.get(5, TimeUnit.SECONDS));
> {code}
> *Actual behavior*
> The accumulators future will never complete for a streaming job when calling
> this just in your main() method from the IDE.
> *Expected behavior*
> Receive the accumulators of the running streaming job.
> The JavaDocs of the method state the following: "Accumulators can be
> requested while it is running or after it has finished.".
> While it is technically true that I can request accumulators, I was expecting
> as a user that I can access the accumulators of a running job.
> Also, I can request accumulators if I submit the job to a cluster.
