-----------------------------------
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.
