> Improvement introduced in https://issues.apache.org/jira/browse/FLINK-14169 does not delete all files in the history server folders completely.
> There is a [json file created for each job|https://github.com/apache/flink/blob/master/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/history/HistoryServerArchiveFetcher.java#L237-L238] in history server's {{webDir/jobs/}} directory. Such file is not deleted by {{cleanupExpiredJobs}}.
> And while the cleaned up job is no longer visible in History server's {{Completed Jobs List}} in web UI, it can be still accessed on {{<HistoryServerURL>/#/job/<jobId>/overview}}.
> While this bug probably won't lead to any serious issues, files in history server's folders should be cleaned up thoroughly.
