[jira] [Created] (MAPREDUCE-2744) [MR-279] In unsercure mode, AM can fake resource requirements

[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: Bug
          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.
