Daryn Sharp commented on YARN-617:
----------------------------------
Does there really need to be different NM behavior? Ie. Why can't the NM
always require container tokens regardless of security setting?
> In unsercure mode, AM can fake resource requirements

> Key: YARN-617
> URL: https://issues.apache.org/jira/browse/YARN-617
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Vinod Kumar Vavilapalli
> Assignee: Vinod Kumar Vavilapalli
> Priority: Minor
>
> Without security, it is impossible to completely avoid AMs faking resources.
> We can at the least make it as difficult as possible by using the same
> container tokens and the RM-NM shared key mechanism over unauthenticated
> RM-NM channel.
> In the minimum, this will avoid accidental bugs in AMs in unsecure mode.
