Other than that, you can find all API incompatible changes from 2.0.x to

Good question... There was a security problem earlier and to address that
we removed it from ContainerLaunchContext.
Today if you check the payload we are sending Container which contains
ContainerToken. ContainerToken is the secured channel for RM to tell NM
about
1) ContainerId
2) Resource
3) User
4) NodeId
It is present there by default (irrespective of security). I hope it
answers your doubt.

With 2.0.x ContainerId was part of the ContainerLaunchContext and I assume
container id was then used to identify what node manager would actually
start.
With 2.1.x ContainerId was removed from ContainerLaunchContext.
ContainerManagementProtocol is only using a list of StartContainerRequest
which have ContainerLaunchContext and Token.
My first question is that if you have different
ContainerLaunchContext(i.e.
command, env variables, etc), how do you know which container is launched
with which launch context?
My second question is how node manager is assosiating allocated
container(which you requested from resource manager) to
ContainerLaunchContext?
