Ubuntu Hadoop群集未启动

我只是设置了一个hadoop集群（namenode+一个datanode）。但是，当我尝试启动hdfs时，会出现以下错误：

hadoop@namenode:/opt/hadoop-2.2.0$ start-dfs.sh
14/01/30 20:18:50 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

我做错了什么？

我刚刚发现这是ubuntu上典型的hadoop错误。此问题的解决方案可在此处找到：

能否显示您的

启动dfs.sh

版本？您如何从项目根目录执行此操作？甚至可能

知道哪个启动dfs.sh

可能很有用。我可以从任何我想要的地方调用start-dfs.sh，因为我做了一个导出路径=$PATH:$HADOOP\u HOME/sbin；）
