>                 URL: https://issues.apache.org/jira/browse/IGNITE-7706
>             Project: Ignite
>          Issue Type: Bug
>          Components: streaming
>            Reporter: Roman Guseinov
>            Priority: Major
>         Attachments: streamer-hangs-issue.zip
> Use case:
> 1. Cache is located only at specific nodes GROUP-1.
> 2. Other nodes GROUP-2 is used for other caches.
> 3. Also, there are nodes for streaming GROUP-3. Cache configuration contains 
> Person class as value type of QueryEntity.
> If we restart GROUP-1 (not all cluster) and restart GROUP-3 with updated 
> configuration and Person class (changed a field type) then streamer hangs 
> (without any messages).
> Reproducer (with README.md) in the attached file (streamer-hangs-issue.zip).
> It seems the problem in handling "Binary type has different field types" 
> exception.
