Description

pontential NPE in checkNodeLabelExpression of SchedulerUtils for nodeLabels.
since we check the nodeLabels null at

        if (!str.trim().isEmpty()
            && (nodeLabels == null || !nodeLabels.contains(str.trim()))) {
          return false;
        }

We should also check nodeLabels null at

      if (!nodeLabels.isEmpty()) {
        return false;
      }
