Summary: Support reservations continue looking for Node Labels
Key: YARN-9903
URL: https://issues.apache.org/jira/browse/YARN-9903
Project: Hadoop YARN
Issue Type: Bug
Reporter: Tarun Parimi
YARN-1769 brought in reservations continue looking feature which improves the
several resource reservation scenarios. However, it is not handled currently
when nodes have a label assigned to them. This is useful and in many cases
necessary even for Node Labels. So we should look to support this for node
labels also.
{code:java}
// TODO, now only consider reservation cases when the node has no label if
(this.reservationsContinueLooking && nodePartition.equals(
RMNodeLabelsManager.NO_LABEL) && Resources.greaterThan( resourceCalculator,
clusterResource, resourceCouldBeUnreserved, Resources.none())) {
{code}
