> Now,  DatanodeInfo will be output in the print log. When we are 
> troubleshooting and searching for slow datanode nodes, we need to convert IP 
> addresses to hostnames, which is quite cumbersome.
> I think the output log should has good readability, so it would be better to 
> output the hostname of the datanode.
