Tao Jie created YARN-6000:
-----------------------------
Summary: 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
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.
