             Summary: 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


*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.
