macos - 已收到，未找到 Hadoop 命令

Question

我是 Hadoop 的新手，尝试在我的 Mac OS X 上安装，当我在终端中运行命令 hadoop version 时，我收到 hadoop 命令未找到的消息。我在这里搜索了帮助文件，但仍有问题..

下面是我在网上找到的 .bashrc 文件

# Set Hadoop-related environment variables
export HADOOP_HOME=/usr/bin/hadoop

# Set JAVA_HOME
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
# Add Hadoop bin/ directory to PATH
export PATH=$PATH:$HADOOP_HOME/bin

这是我的 java 位置的 hadoop-env.sh 文件

# The java implementation to use.
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home

我的hadoop安装位于/usr/bin/hadoop

Answer 1

$cd ~
$vi .bashrc

paste following to the end of the file

#Hadoop variables
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk
export HADOOP_INSTALL=/usr/bin/hadoop
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
###end of paste

$ cd /usr/bin/hadoop/etc/hadoop
$ vi hadoop-env.sh

#modify JAVA_HOME
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/
