[jira] [Created] (FLINK-8181) Kafka producer's FlinkFixedPartitioner returns different partitions when a target topic is rescaled

Tzu-Li (Gordon) Tai created FLINK-8181:
------------------------------------------

             Summary: Kafka producer's FlinkFixedPartitioner returns different partitions when a 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.

The {{FlinkFixedPartitionerTest}} should also be strengthened to cover the target topic rescaling case.
