> for (HostLevelParamsUpdateEvent hostLevelParamsUpdateEvent :
> hostLevelParamsUpdateEvents) {
> hostLevelParamsHolder.updateData(hostLevelParamsUpdateEvent);
> }
> {code}
> *Reason :* With perf->trunk->feature branch merge, we have started using
> *hostLevelParamsHolder*, which has not been initialized/injected. Similarly
> for others : 'topologyHolder' and 'recoveryConfigHelper'.
> *Fix* : Added initialization code for them.
