--------------------------
Component/s: yarn
fairscheduler
> Set modifier of interface Listener in AllocationFileLoaderService to public
> ---------------------------------------------------------------------------
>
> Key: YARN-6000
> URL: https://issues.apache.org/jira/browse/YARN-6000
> Project: Hadoop YARN
> Issue Type: Bug
> Components: fairscheduler, yarn
> Affects Versions: 3.0.0-alpha1
> Reporter: Tao Jie
>
> 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.
