Wanqiang Ji commented on YARN-9502:
-----------------------------------
I reproduced it by modify the method that add new statement
*Thread.sleep(1000);* before *updateRelaxLocalityRequestSchedule* in my local
environment.
Such as:
{code:java}
@Test
public void testRelaxLocalityPreemptionWithNoLessAMInRemainingNodes()
throws Exception {
takeAllResources("root.preemptable.child-1");
RMNode node1 = rmNodes.get(0);
setNumAMContainersOnNode(3, node1.getNodeID());
RMNode node2 = rmNodes.get(1);
setAllAMContainersOnNode(node2.getNodeID());
ApplicationAttemptId greedyAppAttemptId =
getGreedyAppAttemptIdOnNode(node2.getNodeID());
Thread.sleep(10000);
updateRelaxLocalityRequestSchedule(node1, GB * 2, 1);
verifyRelaxLocalityPreemption(node2.getNodeID(), greedyAppAttemptId, 6);
}
{code}
