> Different with YARN-5098, this happens at NM side. When NM recovers, credentials are
read from NMStateStore. When initialize app aggregators, exception happens because of the
overdue tokens. The app is a long running service.
> {code:title=LogAggregationService.java}
>   protected void initAppAggregator(final ApplicationId appId, String user,
>       Credentials credentials, ContainerLogsRetentionPolicy logRetentionPolicy,
>       Map<ApplicationAccessType, String> appAcls,
>       LogAggregationContext logAggregationContext) {
>     // Get user's FileSystem credentials
>     final UserGroupInformation userUgi =
>         UserGroupInformation.createRemoteUser(user);
>     if (credentials != null) {
>       userUgi.addCredentials(credentials);
>     }
>    ...
>     try {
>       // Create the app dir
>       createAppDir(user, appId, userUgi);
>     } catch (Exception e) {
>       appLogAggregator.disableLogAggregation();
>       if (!(e instanceof YarnRuntimeException)) {
>         appDirException = new YarnRuntimeException(e);
>       } else {
>         appDirException = (YarnRuntimeException)e;
>       }
>       appLogAggregators.remove(appId);
>       closeFileSystems(userUgi);
>       throw appDirException;
>     }
> {code}
