------------------------------
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.
