> After HDFS-7645, the namenode can return non-null {{rollingUpgradeInfo}} in heatbeat
reponses. 2.7.1 or 2.6.x datanodes won't finalize the upgrade because it's not null.
> NN might have to check the DN version and return different {{rollingUpgradeInfo}}.
> HDFS-8656 recognized the compatibility issue of the changed semantics, but unfortunately
did not address the semantics of the heartbeat response.
