Blocker Description
The error is reproduced with "streaming.wordcount" example.
- Start instance of ExampleNodeStartup
- Start StreamWords instance
- Start QueryWords instance
- Watch query results coming
- Start another ExampleNodeStartup instance.
On the new ExampleNodeStartup I get the following error:
