                 Key: IGNITE-885
                 URL: https://issues.apache.org/jira/browse/IGNITE-885
             Project: Ignite
          Issue Type: Bug

The error is reproduced with "streaming.wordcount" example.

# Start {{QueryWords}} instance
# Watch query results coming
# Start another {{ExampleNodeStartup}} instance.

On the new {{ExampleNodeStartup}} I get the following error:
