> DataNode conf page cannot display the current value after reconfig
> -------------------------------------------------------------------

> Key: HDFS-13195
> URL: https://issues.apache.org/jira/browse/HDFS-13195
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 2.7.1
> Reporter: maobaolong
> Priority: Minor
> Fix For: 2.7.1

> Attachments: HDFS-13195-branch2.7.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.
