Hadoop 警告消息 : 'execstack -c ' , 或将其与 '-z noexecstack' 链接

Question

我是hadoop新手，在centos box上安装了hadoop 2.2.0。对于我在下面运行的任何 hdfs 命令，都是我收到的警告消息。感谢您的帮助。

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /data/hadoop-2.2.0/lib/native/libhadoop.so.1.0.0 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 <libfile>', or link it with '-z noexecstack'.
14/02/25 11:52:45 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable.

JAVA_HOME设置为oracle热点jdk1.7

能够得到一些答案，centos 运行在 64 位版本上，hadoop 默认安装是 32 位。所以要么需要在centos上编译，要么忽略。
