> target topic is rescaled

> Key: FLINK-8181
> URL: https://issues.apache.org/jira/browse/FLINK-8181
> Project: Flink
> Issue Type: Bug
> Components: Kafka Connector
> Affects Versions: 1.4.0, 1.5.0
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Priority: Blocker
> Fix For: 1.4.0, 1.5.0
>
>
> On fixing FLINK-6288 and migrating the original {{FlinkFixedPartitioner}} to
> the new partitioning API (commit 9ed9b68397b51bfd2b0f6e532212a82f771641bd),
> the {{FlinkFixedPartitioner}} no longer returns identical target partitions
> once a target topic is rescaled.
> This results in a behavioral regression when the {{FlinkFixedPartitioner}} is
> used.
> The {{FlinkFixedPartitionerTest}} should also be strengthened to cover the
> target topic rescaling case.
