> 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~
