Subject [jira] [Created] (IGNITE-7706) Data streamer hangs due to uploading instances of updated class

--------------------------------------

             Summary: Data streamer hangs due to uploading instances of updated class
                 Key: IGNITE-7706
                 URL: https://issues.apache.org/jira/browse/IGNITE-7706
             Project: Ignite
          Issue Type: Bug
          Components: streaming
            Reporter: Roman Guseinov


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.
