             Summary: Method getStarvedResourceRequests() only consider the first encountered resource
                 Key: YARN-7903
                 URL: https://issues.apache.org/jira/browse/YARN-7903
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 3.1.0
            Reporter: Yufei Gu


We need to specify rack and ANY while submitting a node local resource request, as YARN-7561 discussed. For example:
{code}
    ResourceRequest nodeRequest =
            createResourceRequest(GB, node1.getHostName(), 1, 1, false);
    ResourceRequest rackRequest =
            createResourceRequest(GB, node1.getRackName(), 1, 1, false);
    ResourceRequest anyRequest =
            createResourceRequest(GB, ResourceRequest.ANY, 1, 1, false);

    List<ResourceRequest> resourceRequests =
            Arrays.asList(nodeRequest, rackRequest, anyRequest);
{code}
However, method getStarvedResourceRequests() only consider the first encountered resource, which most likely is ResourceRequest.ANY. That's a mismatch for locality request.
