Alejandro Abdelnur commented on YARN-710:
-----------------------------------------
[~vinodkv], the description of the JIRA states what is the use case. From Yarn
public API it is not possible to get hold of the PB instances unless you use
private classes and naming assumptions. This is what the attached patch does,
with the intention of keeping it private to YARN while exposing a simple
write()/read() API. If you have any, I'd like to hear of other alternatives to
address this JIRA.

> I order to do things like AMs failover and checkpointing I need to serialize
> app IDs, app attempt IDs, containers and/or IDs, resource requests, etc.
> Because we are wrapping/hiding the PB implementation from the APIs, we are
> hiding the built in PB ser/deser capabilities.
