> Instead of forwarding the Datanode's software version like it does currently,
> SCM should forward the apparent version to use for writes based on the
> cluster's finalization status. The DatanodeDetails object currently has two
> version fields: currentVersion tracks the Datanode's software version, and
> initialVersion tracks the software version it was first initialized with. We
> will need to decide whether we should repopulate currentVersion with the
> pipeline version at SCM before giving the datanodeDetails to the client, or
> if we should create a new field for pipeline version. Note that old clients
> will be deserializing the currentVersion field from the proto to use for
> server side versioning checks already.
