为什么自制的Hadoop 2.3不能运行OSX Mavericks？

使用自制软件安装hadoop后,我遇到了以下问题.我按照指南在这里:

http://glebche.appspot.com/static/hadoop-ecosystem/hadoop-hive-tutorial.html

在bashrc中设置以下环境变量:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home
export HADOOP_INSTALL=/usr/local/Cellar/hadoop/2.3.0
export HADOOP_HOME=$HADOOP_INSTALL
export PATH=$PATH:$HADOOP_INSTALL/bin
export PATH=$PATH:$HADOOP_INSTALL/sbin
export HADOOP_MAPRED_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_HOME=$HADOOP_INSTALL
export HADOOP_HDFS_HOME=$HADOOP_INSTALL
export YARN_HOME=$HADOOP_INSTALL

运行hadoop namenode -format之后..我尝试运行start-dfs.sh并获取以下内容:

14/05/05 21:19:27 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

如何解决这个问题？
