                 URL: https://issues.apache.org/jira/browse/KAFKA-5556
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 0.11.0.0, 0.10.2.1
            Reporter: Damian Guy


From the user list:
I have been running a streaming application on some data set. Things
usually run ok. Today I was trying to run the same application on Kafka
(ver 0.10.2.1 on Scala 2.12) installed in a Mesos DC/OS cluster. After
running for quite some time, I got the following exception ..
{code}
Exception in thread "StreamThread-1" java.lang.IllegalStateException:

{code}

Looks like we should check if the future is done, i.e., check the return value from poll and retry if time is remaining and {{!future.isDone()}}
