public enum EventType
extends Enum<EventType>

List of all HBase event handler types. Event types are named by a convention: event type names specify the component from which the event originated and then where its destined -- e.g. RS2ZK_ prefix means the event came from a regionserver destined for zookeeper -- and then what the even is; e.g. REGION_OPENING.

We give the enums indices so we can add types later and keep them grouped together rather than have to add them always to the end as we would have to if we used raw enum ordinals.
