> 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. I think it is no 
> need to keep MIN_WAIT_DEAD_SERVER logic. Use backoff sleeping logic is ok for 
> most cases.
