> We removed public modifier of {{AllocationFileLoaderService.Listener}} in YARN-4997 since it trigger a findbugs warning. However it breaks Hive code in {{FairSchedulerShim}}. 
> {code}
> AllocationFileLoaderService allocsLoader = new AllocationFileLoaderService();
>     allocsLoader.init(conf);
>     allocsLoader.setReloadListener(new AllocationFileLoaderService.Listener() {
>       @Override
>       public void onReload(AllocationConfiguration allocs) {
>         allocConf.set(allocs);
>       }
>     });
>     try {
>       allocsLoader.reloadAllocations();
>     } catch (Exception ex) {
>       throw new IOException("Failed to load queue allocations", ex);
>     }
>     if (allocConf.get() == null) {
>       allocConf.set(new AllocationConfiguration(conf));
>     }
>     QueuePlacementPolicy queuePolicy = allocConf.get().getPlacementPolicy();
>     if (queuePolicy != null) {
>       requestedQueue = queuePolicy.assignAppToQueue(requestedQueue, userName);
> {code}
> As a result we should set the modifier back to public.
