    Description

      After upgrading to a new release, the procedure to rollback to older release is to start the namenode in older release with -rollback option.

      As reported in HADOOP-8371, the rollback was allowed on the newer release. During rollback, namenode must allow rollback only if the layout version of the namenode matches that of the layout version in the snapshot that the namenode is rolling back to.
