我正在安装一个hadoop集群，当我启动服务并使用jps时，我会在namenode中得到这个结果。

[hadoop@hadoop-master Desktop]$ jps
5450 ResourceManager
5292 SecondaryNameNode
5708 Jps
5103 NameNode

这个在datanode中

2662 DataNode
2877Jps
2772 NodeManager

但我的datanode仍然没有运行或配置。报告显示了这一点

15/12/21 01:12:58 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

我的配置有什么问题？
