>
> hadoop dfsadmin -refreshNodes reads files defined by _dfs.hosts_ and
> _dfs.hosts.exclude_. If these values are not defined during namenode startup,
> then refreshNodes command assumes there are no files. So, while namenode is
> running, once cannot just edit the config file and add entries to these
> config variables and expect the namenode to read them. Namenode should
> re-read the config file for these variables (_dfs.hosts_ and
> _dfs.hosts.exclude_) when refreshNodes command is invoked.
