> Currently the "DatanodeDetails" are stored in Recon's local DB. Once a 
> datanode has registered the content of DatanodeDetails won't be changed.
> We met a scenario that datanodes' hostname is changed after running a while 
> in Ozone cluster, the hostname in Recon's UI will still show the old 
> hostnames.
> This ticket proposes to send "reregisterCommand" to datanodes if the 
> information of the datanode is changed.
