>
> Key: MAPREDUCE-2744
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2744
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: mrv2, security
> Affects Versions: 0.23.0
> Reporter: Vinod Kumar Vavilapalli
> Priority: Minor
> Fix For: 0.24.0
>
>
> 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.
