------------------------------------------

             Summary: Kafka Consumer checkpointed state may contain undefined offsets
                 Key: FLINK-5849
                 URL: https://issues.apache.org/jira/browse/FLINK-5849
             Project: Flink
          Issue Type: Bug
          Components: Kafka Connector
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai
            Priority: Critical


This is a regression due to FLINK-4280.

In FLINK-4280, all initial offset determination was refactored to be consolidated at the start of {{AbstractFetcher#runFetchLoop}}. However, this caused checkpoints that were triggered before the method was ever reached to contain undefined partition offsets.
