Yun Tang created FLINK-14707:
--------------------------------
Summary: Refactor checkpoint related methods within Environment
Key: FLINK-14707
URL: https://issues.apache.org/jira/browse/FLINK-14707
Project: Flink
Issue Type: Improvement
Reporter: Yun Tang
Fix For: 1.10.0
After FLINK-7720 fixed, the two methods of
{{Environment#acknowledgeCheckpoint}} have been actually useless, and their
usage have been overridden by {{TaskStateManager#reportTaskStateSnapshots}}.
More generally, we would consider {{Environment}} interface as getter to access
components instead of doing real actions. I prefer to remove
{{acknowledgeCheckpoint}} and {{declineCheckpoint}} methods or at least
deprecated them.
