Jeff Zhang updated TEZ-1384:
----------------------------
Description:
Currently each entity (DAG, Vertex, Task, TaskAttempt) has some common recovery
code like log history event and restore from history event. These are 2
opposite aspects of recovery. One for store status while the other is for
restore status. This jira is for putting these pieces of code together ( in an
inner class ). In this way, it is easy to maintain and cut down the possibility
that one field is not stored or restored.
> Move recovery related code into inner class
