> YARN-6678 have fixed the IllegalStateException problem but the debug log it added may cause NPE when trying to print containerId of non-existed reserved container on this node. Replace {{schedulerContainer.getSchedulerNode().getReservedContainer().getContainerId()}} with {{schedulerContainer.getSchedulerNode().getReservedContainer()}} can fix this problem.
