          Issue Type: Improvement
    Affects Versions: 0.4.0
            Reporter: Jeff Zhang
            Assignee: Jeff Zhang


Almost all our entities (Vertex, Task etc) are state machine based and written using a formal state machine. But DAGAppMaster is not written on a formal state machine even though it has a state machine based behavior. This jira is for refactoring it into state machine based
