我正在尝试使用本教程 http://codesfusion.blogspot.gr/2013/10/setup-hadoop-2x-220-on-ubuntu.html?m=1 在计算机上的单节点群集上安装 Hadoop 2.2.0。我一步一步地遵循我看到的每一条指令，但我每次都遇到同样的问题。NameNode 、DataNode 和 SecondaryNameNode 未运行。当我输入 start-dfs.sh 、 start-yarn.sh 和 jps 时，我看到的消息是：
hduser@victor-OEM:/usr/local/hadoop/sbin$ start-dfs.sh
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
Starting namenodes on []

Are you sure you want to continue connecting (yes/no)? yes

你可以试试这个链接：Leraning hadoop。 它适用于 0.23.9，但也适用于 2.2.0
某些版本的代码融合教程（例如此版本）省略了代码块中的 xml 标记，以便：
#add this to foo.txt
<bizz>bar</bizz>
成为：
#add this to foo.txt
bar
在配置中包含 xml 标记解决了该问题。
在 hadoop-env.sh 中禁用 IPv6：
export HADOOP_OPTS=-Djava.net.preferIPv4Stack=true
我遇到了同样的问题。
我通过禁用防火墙解决了它。
只需使用此命令
sudo ufw disbale
我尝试了以下步骤：
-
ssh-keygen -t rsa -P "
-
cat $HOME/.ssh/id_rsa.pub>> $HOME/.ssh/authorized_keys
之后，打开一个新终端并启动Hadoop集群，这解决了我的问题。
