------------------------------------
Thanks [~bibinchundatt] for the review! [^YARN-7599-YARN-7402.v5.patch]
uploaded with fixes.
bq. 4. Rename testcase name -> testBasicCase
This is already the test case name, typo?
bq. 1. During long maintainance period of cluster, We might require option to
disable cleaner at run time. rt ??
Application cleaner is disabled when
YarnConfiguration.GPG_APPCLEANER_INTERVAL_MS is set to zero or negative value:
{code:java}
120 long appCleanerIntervalMs =
121
getConfig().getLong(YarnConfiguration.GPG_APPCLEANER_INTERVAL_MS,
122 YarnConfiguration.DEFAULT_GPG_APPCLEANER_INTERVAL_MS);
123 if (appCleanerIntervalMs > 0) {
124
this.scheduledExecutorService.scheduleAtFixedRate(this.applicationCleaner,
125 0, appCleanerIntervalMs, TimeUnit.MILLISECONDS);
{code}

> 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
