Roman Guseinov reassigned IGNITE-7706:
--------------------------------------
Assignee: Roman Guseinov
> 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
> Assignee: 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.
