> Region normalizer chore thread is getting killed when the region is not found on any server.
> As per the method
> {code:java}
> // code placeholder
> /**
>  * @param serverName
>  * @return ServerLoad if serverName is known else null
>  */
> public ServerLoad getLoad(final ServerName serverName) {
