WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Starting namenodes on [Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /opt/hadoop-2.6.0/lib/native/libhadoop.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It‘s highly recommended that you fix the library with ‘execstack -c ‘, or link it with ‘-z noexecstack‘.
这是因为hadoop默认编译好的native库是32bit的，所以要重新编译hadoop2.6的源代码，获取64位native库，将其复制到原来安装的hadoop的native目录中替代原来的类库，然后重新运行即可。
百度搜索下载native-x64.rar
