> Similar problem has been fixed with HDFS-7185. Recent change in HDFS-8432
> brings this back.
> With HDFS-8432, the primary NN will not update the VERSION file to the new
> version after running with "rollingUpgrade" option until upgrade is
> finalized. This is to support more downgrade use cases.
> However, the checkpoint on the SNN is incorrectly updating the VERSION file
> when the rollingUpgrade is not finalized yet on the primary NN. As a result,
> the SNN checkpoint successfully but fail to push it to the primary NN because
> its version is higher than the primary NN as shown below.
