Answer 1

我有同樣的問題！ 我解決了不斷變化的.bashrc文件。 將這些行添加到$ HOME / .bashrc文件的末尾，更改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>

我希望這可以幫助某人
