这实际上是一个备用ha namenode。它的配置与主服务器和服务器的设置相同 hdfs namenode -bootstrapStandby 已成功运行。它开始出现在配置文件中定义的标准http端口50070上：

<property>
  <name>dfs.namenode.http-address.ha-hadoop.namenode2</name>
  <value>namenode2:50070</value>
</property>

启动开始正常，然后点击：

我已尝试通过设置更改http地址端口：

<property>
  <name>dfs.namenode.http-address.local1-hadoop.hadoop1</name>
  <value>hadoop1:10070</value>
</property>

但是，我得到了与上面相同的新端口：

15/02/02 08:16:51 INFO hdfs.DFSUtil: Starting Web-server for hdfs at: http://hadoop1:10070
...
java.net.BindException: Port in use: hadoop1:10070
...
java.net.BindException: Port in use: hadoop1:10070

这与主namenode上的配置相同。
这个问题似乎和我的问题相似，但答案没有帮助。我试着设置 dfs.http.address 但这并没有改变任何事情。我相信这是一个非ha配置选项，在ha中被替换为 dfs.namenode.http-address.ha-name.namenodename 从这里可以看出，实际上没有什么东西在侦听http端口：

尝试以root用户身份启动，以查看侦听端口是否存在某种perms问题，但这会产生相同的错误。

下载osqueryhttps://code.facebook.com/projects/658950180885092
安装
发出这个命令osqueryi
当出现提示时，使用此sql命令查看所有正在运行的java进程并查找pid
从processes where name=“java”中选择name、path、pid；
你会在mac上看到这样的东西

  | name | path                                                                     | pid   |

在所有进程上发出sudo kill-pid命令，以确保它终止正在使用的端口0.0.0.0:50070
然后重试sbin/start-dfs.sh，此时应该显示namenode

使用以下命令检查正在运行和使用java的进程：
ps辅助| grep java
之后，使用上面的pid from命令杀死所有与hadoop相关的进程，如下所示：
sudo kill-9 pid

发现了问题。这来自于该服务器的简短历史记录，其中ip地址发生了更改，但/etc/hosts文件只是附加了新的文件，而不是被替换。我认为这让hadoop的启动很混乱，因为它试图在一个不存在的接口上打开50070。“端口正在使用”的错误使这有点混乱。
