>       if (response.getAreNodeLabelsAcceptedByRM() && LOG.isDebugEnabled()) {
>           LOG.debug("Node Labels {" + StringUtils.join(",", previousNodeLabels)
>               + "} were Accepted by RM ");
>         } else {
>           // case where updated labels from NodeLabelsProvider is sent to RM and
>           // RM rejected the labels
>           LOG.error(
>               "NM node labels {" + StringUtils.join(",", previousNodeLabels)
>                   + "} were not accepted by RM and message from RM : "
>                   + response.getDiagnosticsMessage());
>         }
>       ... ...
> {code}
> When LOG.isDebugEnabled() is false, NM will always print error log. It is an obvious
error and is so misleading.
