----------------------------------------
Thanks [~botong] for updated patch

Application cleaner is disabled when
YarnConfiguration.GPG_APPCLEANER_INTERVAL_MS is set to zero or negative value:
{quote}
# I was thinking of disabling cleaner while the GPG service is live. Shell
command to reset clean interval. Similar to
{{HSAdminServer#refreshLogRetentionSettings}}. As future work
# Related to testcase name,IMHO better rename to testFederationStoreAppsCleanUp.
# Can you change to single configuration similar to
dfs.http.client.retry.policy.spec {min,max,interval}. Any comments on this
point?

61 LOG.debug("List of apps: ",
routerApps.stream().map(Object::toString)
62 .collect(Collectors.joining(",")));

{code}
# Regarding logs, i think better to print candidates for delete . Instead of
all apps
# Handle checkstyle issues .I am not able to CI results now.

> In Federation, we need a cleanup service for StateStore as well as Yarn
> Registry. For the former, we need to remove old application records. For the
> latter, failed and killed applications might leave records in the Yarn
> Registry (see YARN-6128). We plan to do both cleanup work in
> ApplicationCleaner in GPG
