Question

我已经安装了hadoop 3.1.0版本并设置了env变量。当我运行$ HADOOP_HOME / bin / hadoop版本时，显示我安装但运行hadoop版本无法找到hadoop命令（在hadoop用户内）我的环境变量如下所示：

#HADOOP VARIABLES START
export HADOOP_HOME=$HOME/usr/local/hadoop
export HADOOP_CONF_DIR=$HOME/usr/local/hadoop/etc/hadoop
export HADOOP_INSTALL=$HOME/usr/local/hadoop
export PATH=$PATH:$HADOOP_INSTALL/bin
export PATH=$PATH:$HADOOP_INSTALL/sbin
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export PATH=$PATH:$HOME/usr/local/hadoop
#HADOOP VARIABLES END

echo $HADOOP_HOME
/usr/local/hadoop

echo $HOME 
/home/hduser



echo $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games


$HADOOP_HOME/bin/hadoop version

似乎我的全局路径无法正常工作。我可能会错过一些东西，我试图弄清楚几个小时，但没有任何作用。非常感谢

从您的echo $PATH结果中，看似hadoop路径未添加到您的PATH。

你在哪里写出口报表？尝试将它们添加到~/.bashrc并开始新的终端。

'$ HADOOP_HOME / bin / hadoop version'工作正常，但'hadoop版'不起作用
