> The HDFS-9426 patches for branch-2.7 and branch-2 used different tag numbers for {{rollingUpgradeStatusV2}}
in HeartbeatResponseProto:
> trunk/branch-2:
> {code}
> message HeartbeatResponseProto {
>   repeated DatanodeCommandProto cmds = 1; // Returned commands can be null
>   required NNHAStatusHeartbeatProto haStatus = 2;
>   optional RollingUpgradeStatusProto rollingUpgradeStatus = 3;
>   optional uint64 fullBlockReportLeaseId = 4 [ default = 0 ];
>   optional RollingUpgradeStatusProto rollingUpgradeStatusV2 = 5;
> }
> {code}
> branch-2.7:
> {code}
> message HeartbeatResponseProto {
>   repeated DatanodeCommandProto cmds = 1; // Returned commands can be null
>   required NNHAStatusHeartbeatProto haStatus = 2;
>   optional RollingUpgradeStatusProto rollingUpgradeStatus = 3;
>   optional RollingUpgradeStatusProto rollingUpgradeStatusV2 = 4;
> }
> {code}
> This breaks rolling upgrade between 2.7 and a future 2.8. We need to renumber the tags
to preserve wire compatibility.
