Ho riscontrato i seguenti problemi dopo aver usato homebrew per installare hadoop. Ho seguito la guida qui:Perché Hadoop 2.3 homebrew non funziona con i Maverick OSX?

Impostazione delle seguenti variabili d'ambiente in bashrc:
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
Dopo l'esecuzione di un -format Hadoop NameNode .. tento di fare funzionare start-dfs.sh e ottenere il seguente:
14/05/05 21:19:27 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

Come ottengo intorno a questo problema?
