我有同樣的問題！我解決了那個改變.bashrc文件。這些行添加到$ HOME/.bashrc文件的末尾，改變了Hadoop的安裝路徑：

<code> 
#Set hadoop-related enviroment variables 
export HADOOP_PREFIX=/usr/local/hadoop-2.7.1 
export HADOOP_HOME=/usr/local/hadoop-2.7.1 
export HADOOP_MAPRED_HOME=${HADOOP_HOME} 
export HADOOP_COMMON_HOME=${HADOOP_HOME} 
export HADOOP_HDFS_HOME=${HADOOP_HOME} 
export YARN_HOME=${HADOOP_HOME} 
export HADOOP_CONFDIR=${HADOOP_HOME}/etc/hadoop 
# Native path 
export HADOOP_COMMON_LIB_NATIVE_DIR=${HADOOP_PREFIX}/lib/native 
export HADOOP_OPTS="-Djava.library.path=${HADOOP_PREFIX}/lib/native" 
export JAVA_LIBRARY_PATH=$HADOOP_HOME/lib/native:$JAVA_LIBRARY_PATH 
# Add Hadoop bin/ directory to PATH 
export PATH=$PATH:$HADOOP_HOME/ 
export PATH=$PATH:$HADOOP_HOME/bin 
</code>
