      Description

      • When starting rolling upgrade, NN should create a checkpoint before it writes the upgrade marker edit log transaction.
      • When rolling upgrade is in progress, NN should reject saveNamespace rpc calls. Further, if NN restarts, it should create a checkpoint only right before the upgrade marker.
