> Recently, I meet one case that NameNode missing block after restart which is 
> related with HDFS-14997.
> a. during NameNode restart, it will return command `DNA_REGISTER` to DataNode 
> when receive some RPC request from DataNode.
> b. when DataNode receive `DNA_REGISTER` command, it will run #reRegister 
> async.
> {code:java}
>   void reRegister() throws IOException {
>     if (shouldRun()) {
>       // re-retrieve namespace info to make sure that, if the NN
>       // was restarted, we still match its version (HDFS-2120)
>       NamespaceInfo nsInfo = retrieveNamespaceInfo();
>       // and re-register
>       register(nsInfo);
>       scheduler.scheduleHeartbeat();
>       // HDFS-9917,Standby NN IBR can be very huge if standby namenode is down
>       // for sometime.
>       if (state == HAServiceState.STANDBY || state == 
> HAServiceState.OBSERVER) {
>         ibrManager.clearIBRs();
>       }
>     }
>   }
> {code}
> c. As we know, #register will trigger BR immediately.
> d. because #reRegister run async, so we could not make sure which one run 
> first between send FBR and clear IBR. If clean IBR run first, it will be OK. 
> But if send FBR first then clear IBR, it will missing some blocks received 
> between these two time point until next FBR.
