Hi, dev. I've been working on FLINK-4492 issue, but couldn't reproduce the bug. As I mentioned in comment<https://issues.apache.org/jira/browse/FLINK-4492?focusedCommentId=15581831&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15581831>, FsCheckpointStreamFactory properly deletes all checkpoint files even if job is cancelled. So the question is if anybody met this bug? Does this issue still persist? Maybe I misunderstood the issue.
