> Operations such as {{addCacheDirectives()}} throws {{SafeModeException}} when 
> the NN is in safemode:
> {code}
>       if (isInSafeMode()) {
>         throw new SafeModeException(
>             "Cannot add cache directive", safeMode);
>       }
> {code}
> While other NN operations throws {{RetriableException}} when HA is enabled:
> {code}
>   void checkNameNodeSafeMode(String errorMsg)
>       throws RetriableException, SafeModeException {
>     if (isInSafeMode()) {
>       SafeModeException se = new SafeModeException(errorMsg, safeMode);
>       if (haEnabled && haContext != null
>           && haContext.getState().getServiceState() == HAServiceState.ACTIVE
>           && shouldRetrySafeMode(this.safeMode)) {
>         throw new RetriableException(se);
>       } else {
>         throw se;
