我将Hadoop 2.8安装到运行Ubuntu 16.04服务器版和OpenJDK 7的Odroid XU4 Armhf设备上，遵循以下Apache指南：https://hadoop.apache.org/docs/r2.8.0/hadoop-project-dist/hadoop-common/SingleCluster.html
一切似乎都没问题，当我运行jps时，我看到以下过程：
- NameNode
- DataNode
- SecondaryNameNode
- ResourceManager
- NodeManager
目前我将Hadoop设置为单节点集群，但是当我运行命令“netstat --listen”时，我看不到Hadoop使用的任何端口。所以端口9000没有打开，或50070.这是我从netstat看到的：
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 127.0.1.1:domain *:* LISTEN
tcp 0 0 *:ssh *:* LISTEN

udp 0 0 *:bootpc *:*
udp 0 0 *:48076 *:*
raw6 0 0 [::]:ipv6-icmp [::]:* 7
当我运行start-dfs.sh时，我看到以下输出：
17/04/28 19:03:37 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

我花了最近三天调试这个，但由于某些原因，Hadoop根本没有打开任何TCP端口。有什么我想念的吗？
我非常感谢帮助。
