Chandni Singh commented on YARN-5015:

@[~leftnoteasy] You are correct that this logic is only needed in the NM. I 
re-examined the changes in YARN-611 and realized it is not needed outside of NM.

I will move it.

> We support sliding window retry policy for AM restarts (Introduced in 
> YARN-611). Similar sliding window retry policy is needed for container 
> restarts.
> With this change, we can introduce a common class for 
> SlidingWindowRetryPolicy ( suggested by [~vvasudev] in the comments) and 
> integrate it to container restart. 
> In a subsequent jira, we can modify the AM code to use 
> SlidingWindowRetryPolicy which will unify the AM and container restart code.
