Xin Chen commented on FLINK-33288:
----------------------------------
[~Zhanghao Chen] Yes, and I'm still a bit confused. You can see that
job-result-store path and HA-storage-appid path is parallel, such as:
{code:java}
/flink/recovery/application_1697525535591_0001
/flink/recovery/job-result-store/application_1697525535591_0001
{code}
and Your code:
{code:java}
final Path clusterHaStoragePath =
HighAvailabilityServicesUtils.getClusterHighAvailableStoragePath(configuration);
{code}
'clusterHaStoragePath ' can be
'/flink/recovery/application_1697525535591_0001', we can delete that. Deleting
it every time does not seem to affect the job-result-store-path:
'/flink/recovery/job-result-store/application_1697525535591_0001'!
So why it can broke the job result store feature?

> Issue Type: Bug
> Components: Runtime / Configuration
> Affects Versions: 1.16.2, 1.17.1
> Reporter: Xin Chen

> 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}
