> Currently, we can enable RM HA configuration without multiple RM ids(YarnConfiguration.RM_HA_IDS).  This behaviour can cause wrong operations. ResourceManager should verify that more than 1 RM id must be specified in RM-HA-IDs.
> One idea is to support "strict mode" to enforce this check as configuration(e.g. yarn.resourcemanager.ha.strict-mode.enabled).
