      This breaks rolling upgrades because it changes the major version of the NM state store schema. Therefore when a new NM comes up on an old state store it crashes.

      The state store versions for this change have been updated in YARN-6798.

      Description

      YARN-1336 added the ability to restart NM without loosing any running containers. In a Federated YARN environment, there's additional state in the AMRMProxy to allow for spanning across multiple sub-clusters, so we need to enhance AMRMProxy to support work-preserving restart.
