> In production env, regionservers may be removed from the cluster for hardware
> problems and rejoined the cluster after the repair. There is a potential risk
> that the version of rejoined regionserver may diff from others because the
> cluster has been upgraded through many versions.
> To solve this, we can show the all regionservers' version in the server list
> of master's status page, and highlight the regionserver when its version is
> different from the master's version, similar to HDFS-3245
> Suggestions are welcome~
