Description

Region normalizer chore thread is getting killed when the region is not found on any server.

As per the method

// code placeholder
/**
 * @param serverName
 * @return ServerLoad if serverName is known else null
 */
public ServerLoad getLoad(final ServerName serverName) {
  return this.onlineServers.get(serverName);
}

 So ideally we should check for the returned null in SimpleRegionNormalizer
