?You have loaded library /usr/local/hdfs/hadoop-2.2.0/lib/native/libhadoop.so.1.0.0 错误。
我的错误提示：

?最后在github上找到解决方案。
最后因为环境变量的问题。后面两个链接也挺不错。
You add a variable on 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"
And.. starting!!
$ start-all.sh
Thanks. :D
