    boolean resetQuota = !options.has("no-reset-quota");
    Set<String> storeNames = Sets.newHashSet();

    QuotaResetter quotaResetter = new QuotaResetter(bootstrapURL, storeNames, rebalancePlan.getFinalCluster().getNodeIds());
    // before rebalance, remember and disable quota enforcement settings
    if (resetQuota) {
        quotaResetter.rememberAndDisableQuota();
    }
    // Plan & execute rebalancing.
    rebalanceController.rebalance(rebalancePlan);
    // after rebalance, reset quota values and recover quota enforcement
    if (resetQuota) {
        quotaResetter.resetQuotaAndRecoverEnforcement();
    }
}
