Abhishek Kapoor commented on YARN-816:
--------------------------------------
Couldn't agree more [~vinodkv]
We can have state of AM communicated to RM.
When AM boots up, the state from RM should be communicated to AM for example
whether its a fresh start or a recovery and if its a recovery the state of the
nodes app was running on, should be communicated to AM by RM.
The above use case might require communication protocol change between AM and
RM ..
