> If RegionServerCallable#prepare failed when getRegionLocation, the location in this callable object is null. And before we retry we will sleep. However, when location is null we will sleep at least 10 seconds. And the request will be failed directly if operation timeout is less than 10 seconds. I think it is no need to keep MIN_WAIT_DEAD_SERVER logic. Use backoff sleeping logic is ok for most cases.
