>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: datanode
>    Affects Versions: 2.7.1
>            Reporter: maobaolong
>            Assignee: maobaolong
>            Priority: Minor
>             Fix For: 2.7.1
>
>         Attachments: HDFS-13195-branch-2.7.001.patch,

>
> Now the branch-2.7 support dfs.datanode.data.dir reconfig, but after i 
> reconfig this key, the conf page's value is still the old config value.
> The reason is that:
> {code:java}
> public DatanodeHttpServer(final Configuration conf,
>       final DataNode datanode,
>       final ServerSocketChannel externalHttpChannel)
>     throws IOException {
>     this.conf = conf;
>     Configuration confForInfoServer = new Configuration(conf);
>     confForInfoServer.setInt(HttpServer2.HTTP_MAX_THREADS, 10);
>     HttpServer2.Builder builder = new HttpServer2.Builder()
>         .setName("datanode")
>         .setConf(confForInfoServer)
>         .setACL(new AccessControlList(conf.get(DFS_ADMIN, " ")))
>         .hostName(getHostnameForSpnegoPrincipal(confForInfoServer))
>         .addEndpoint(URI.create("http://localhost:0";))
>         .setFindPort(true);
>     this.infoServer = builder.build();
> {code}
> The confForInfoServer is a new configuration instance, while the dfsadmin 
> reconfig the datanode's config, the config result cannot reflect to 
> confForInfoServer, so we should use the datanode's conf.
