> Key: IGNITE-5195
> URL: https://issues.apache.org/jira/browse/IGNITE-5195
> Project: Ignite
> Issue Type: Bug
> Components: streaming
> Affects Versions: 1.8
> Reporter: Andrew Mashenkov
> Assignee: Mikhail Cherkasov
> Fix For: 2.4

> Attachments: DataStreamerFailure.java
>
>
> DataStreamer failed with "too many remaps" message even if non-data node
> enter\leave topology.
> PFA repro attached.
> Seems, we should ignore topology changes when non-data node enter\leave the
> grid.
> And also we need to sure that remapping doesn't occurs when there is no data
> nodes in grid any more, as remapping make no sense and more suitable message
> should be logged.
