      Description

      AM uses the NMToken to authenticate all the AM-NM communication.
      NM will validate NMToken in below manner

      • If NMToken is using current or previous master key then the NMToken is valid. In this case it will update its cache with this key corresponding to appId.
      • If NMToken is using the master key which is present in NM's cache corresponding to AM's appId then it will be validated based on this.
      • If NMToken is invalid then NM will reject AM calls.

      Modification for ContainerToken

      • At present RPC validates AM-NM communication based on ContainerToken. It will be replaced with NMToken. Also now onwards AM will use NMToken per NM (replacing earlier behavior of ContainerToken per container per NM).
      • startContainer in case of Secured environment is using ContainerToken from UGI YARN-617; however after this it will use it from the payload (Container).
      • ContainerToken will exist and it will only be used to validate the AM's container start request.
