Subject [jira] [Updated] (FLINK-8181) Kafka producer's FlinkFixedPartitioner returns different partitions when a target topic is rescaled
Date Fri, 01 Dec 2017 05:20:00 GMT

     [ https://issues.apache.org/jira/browse/FLINK-8181?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tzu-Li (Gordon) Tai updated FLINK-8181:
---------------------------------------
    Description: 
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.
