@HeartSaVioR, you are right, I did not notice the `DisruptorQueueTest`
failure.
@srdo, Thank you for putting up #1421. It's ironic to see `LocalNimbusTest`
fail for that PR. :) I am bumping this on up.

> Running local clusters without simulating time breaks
> Testing.completeTopology, and may cause message loss
> ----------------------------------------------------------------------------------------------------------
>
> Key: STORM-1837
> URL: https://issues.apache.org/jira/browse/STORM-1837
> Project: Apache Storm
> Issue Type: Bug
> Affects Versions: 1.0.0, 2.0.0, 1.0.1
> Reporter: Stig Rohde Døssing
> Priority: Minor
>
> Since https://github.com/apache/storm/pull/810 it is no longer possible to
> call Testing.completeTopology when time is not simulating, because a call to
> advance-cluster-time is made from the function, which calls Time/advanceTime.
> advance-cluster-time should only be called if time is simulating.
> Since https://github.com/apache/storm/pull/830 a local cluster run without
> time simulation may lose messages. When a worker emits messages for a worker
> that hasn't started yet, the message is lost. This can happen because spouts
> may start emitting before all workers have started, when time simulation is
> disabled. Local clusters usually run without message timeouts, so this will
> make tests relying on Testing.withLocalCluster flaky.
> The problem is that there are no longer any queues to store messages for
> workers that haven't started yet. See
> https://github.com/apache/storm/pull/830/files#diff-c6ff4208ef84c7a5a1a6b8b6bd1f7d19R104.
> A queue should be added for messages for workers that haven't registered a
> receive callback yet.
