----------------------------------
[~mapohl][~Zhanghao Chen] Thank you for your discussion. I'll move to pay
attention to FLINK-30513.
> Empty directory residue with appid name in HA(highly-available) related
> directory of hdfs, not cleaned

> Key: FLINK-33288
> URL: https://issues.apache.org/jira/browse/FLINK-33288
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Configuration
> Affects Versions: 1.16.2, 1.17.1
> Reporter: Xin Chen
> Priority: Major
> Attachments: image-2023-10-17-16-43-07-859.png, screenshot-1.png,

> When I submitted a large number of tasks in Flink-on-Yarn mode and
> successfully executed, I unexpectedly found a large number of empty
> directories left in the directory related to 'high availability.storageDir'
> on hdfs, with appids as shown below. I believe this must be cleared! However,
> after verification in the environments of 1.16.2 and 1.17.1, it was proven
> that neither of them solved this problem.
> my flink-conf.yaml about 'high availability.storageDir':
> {code:java}
> high-availability.storageDir: hdfs://hdfsHACluster/flink/recovery
> {code}
