我正在尝试使用本教程在我的计算机上的单节点集群上安装hadoop2.2.0http://codesfusion.blogspot.gr/2013/10/setup-hadoop-2x-220-on-ubuntu.html?m=1 . 我遵循我看到的每一个指示，一步一步，但我每次都有同样的问题。namenode、datanode和secondarynamenode未运行。输入start-dfs.sh、start-yarn.sh和jps时看到的消息是：
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.
