Arun Suresh commented on YARN-5087:
-----------------------------------

[~kasha], what I meant was.. Given that the allocate response already contains 
a {{allocated_containers}} list. And given that one can query the Resource 
Capability as well as the container execution type from the Container record.. 
I was wondering if we really need the {{increased_containers}} and 
{{decreased_containers}} field in the AllocateResponse as well.

A updated container can be returned in the {{allocated_containers}} list and 
the AM can just compare with its existing container to examine what has been 
updated.

> Expose API to allow AM to request for change of container ExecutionType
