             Summary: Change InputInitializerContext.registerForVertexStateUpdates to return a list of pending state changes
                 Key: TEZ-1546
                 URL: https://issues.apache.org/jira/browse/TEZ-1546
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth
            Priority: Critical


Sending pending events via the stateChange on the InputInitializer can be confusing - since multiple calls will be made back to back, without knowing how many events are coming in , and which the last one is.
Returning all past state changes via register ensures invocations of onStateChanged are current events.
