Java HotSpot(TM) 64-Bit Server VM warning:You have loaded library /usr/local/hadoop-2.4.0/lib/native/libhadoop.so.1.0.0which might have disabled stack guard. The VM will try to fix the stack guardnow.

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

解决方案：

添加如下信息到 hadoop-env.sh and yarn-env.sh.

export HADOOP_COMMON_LIB_NATIVE_DIR=${HADOOP_PREFIX}/lib/native

export HADOOP_OPTS="-Djava.library.path=$HADOOP_PREFIX/lib"

HADOOP_PREFIX 是hadoop 的目录 需要在环境变量中配置，如果不配置，下面直接写hadoop全路径.

如果配置仍然报错，可能是因为机器是64位而本地库是在 32位下编辑的，需要重新在64位下编译。

下面是编译好的64位native

64位nativa
