> Even though RegionStates is a highly accessed data structure in HMaster. Most 
> of it's methods are synchronized. Which limits concurrency. Even simply 
> making some of the getters non-synchronized by using concurrent data 
> structures has helped with region assignments. We can go as simple as this 
> approach or create locks per region or a bucket lock per region bucket.
