Vinod Kumar Vavilapalli commented on YARN-613:
----------------------------------------------
bq. Question: How do you plan for NMs to authenticate the AM tokens?
I thought I covered it but missed stating that - RM will share the underlying
secret key corresponding to AM tokens as part of node-registration just like
the one corresponding to ContainerTokens.
> Create NM proxy per NM instead of per container
