      Description

      Today if AMs go down,

      • RM kills all the containers of that ApplicationAttempt
      • New ApplicationAttempt doesn't know where the previous containers are running
      • Old running containers don't know where the new AM is running.

      We need to fix this to enable work-preserving AM restart. The later two potentially can be done at the app level, but it is good to have a common solution for all apps where-ever possible.
