Examples of ContainerToken

org.apache.hadoop.yarn.api.records.ContainerToken

ContainerToken is the security token used by the framework to verify authenticity of any Container.

The ResourceManager, on container allocation provides a secure token which is verified by the NodeManager on container launch.

Applications do not need to care about ContainerToken, they are transparently handled by the framework - the allocated Container includes the ContainerToken.

        unreserve(application, priority, node, rmContainer);
      }


      // Create container tokens in secure-mode
      if (UserGroupInformation.isSecurityEnabled()) {
        ContainerToken containerToken = 
            createContainerToken(application, container);
        if (containerToken == null) {
          // Something went wrong...
          return Resources.none();
        }
