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

             Summary: CheckpointCoordinatorConfiguration#isExactlyOnce() is inconsistent with StreamConfig#getCheckpointMode()
                 Key: FLINK-17107
                 URL: https://issues.apache.org/jira/browse/FLINK-17107
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Checkpointing
            Reporter: Yingjie Cao


CheckpointCoordinatorConfiguration#isExactlyOnce() is inconsistent with StreamConfig#getCheckpointMode() when checkpoint is disabled. CheckpointCoordinatorConfiguration#isExactlyOnce() returns true if checkpoint mode is  EXACTLY_ONCE mode and return false if checkpoint mode is AT_LEAST_ONCE while StreamConfig#getCheckpointMode() will always return AT_LEAST_ONCE which means always not exactly once.
