------------------------------------
Summary: Remove the clusterResource param from
RMNodeLabelsManager.getResourceByLabel
Key: YARN-10994
URL: https://issues.apache.org/jira/browse/YARN-10994
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Benjamin Teke
RMNodeLabelsManager.getResourceByLabel has currently two parameters: String
label and Resource clusterResource. The latter however is only used by tests
during mocking: the parameter supplied in the production code by the callers
are returned in tests. See ReservationSystemTestUtil.createRMContext:
{code:java}
...
when(nlm.getResourceByLabel(any(), any(Resource.class)))
.thenAnswer(new Answer<Resource>() {
@Override
public Resource answer(InvocationOnMock invocation) throws Throwable {
Object[] args = invocation.getArguments();
return (Resource) args[1];
}
});
...
{code}
This is misleading and hard to understand (no way of knowing with what values
are the clusterResources mocked by looking at the tests) and generates
unnecessary production code so it should be removed and the tests should be
properly mocked.
