> In existing implementation, when parsing node-to-labels mapping from RMAdminCLI, it transferred all labels to lowercase:
> {code}
>       for (int i = 1; i < splits.length; i++) {
>         if (!splits[i].trim().isEmpty()) {
>           map.get(nodeId).add(splits[i].trim().toLowerCase());
>         }
>       }
> {code}
> That is not correct, we should fix that.
