-----------------------------------------------
Issue Type: Sub-task (was: Bug)
Parent: MAPREDUCE-3101
> [MR-279] In unsercure mode, AM can fake resource requirements
> --------------------------------------------------------------
>
> Key: MAPREDUCE-2744
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2744
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: mrv2
> Reporter: Vinod Kumar Vavilapalli
> Fix For: 0.23.0
>
>
> 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.
