mac下快速安装hadoop的好方法

相信使用ma时间长一点的朋友都一定听说过homebrew。

homebrew 是mac下3个主流的package management tool之一。没有安装的朋友可以直接在终端中运行如下指令完成brew的安装

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

这样在mac下，再安装hadoop也就非常简单啦。

首先运行

brew info hadoop

得到当前版本信息

hadoop: stable 2.3.0
http://hadoop.apache.org/
Not installed
From: https://github.com/Homebrew/homebrew/commits/master/Library/Formula/hadoop.rb
==> Caveats
In Hadoop's config file:
/usr/local/Cellar/hadoop/2.3.0/libexec/etc/hadoop/hadoop-env.sh,
/usr/local/Cellar/hadoop/2.3.0/libexec/etc/hadoop/mapred-env.sh and
/usr/local/Cellar/hadoop/2.3.0/libexec/etc/hadoop/yarn-env.sh
$JAVA_HOME has been set to be the output of:
/usr/libexec/java_home

 

然后进行安装

 brew install hadoop

返回：

Warning: It appears you have MacPorts or Fink installed.
Software installed with other package managers causes known problems for
Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again.
==> Downloading http://www.apache.org/dyn/closer.cgi?path=hadoop/core/hadoop-2.2.0/hadoop-2.2.0.tar.gz
==> Best Mirror http://mirrors.hust.edu.cn/apache/hadoop/core/hadoop-2.2.0/hadoop-2.2.0.tar.gz

最后完成。

 

如果选择版本安装可以先进行查看版本

brew versions hadoop

返回：
Warning: brew-versions is unsupported and may be removed soon.
Please use the homebrew-versions tap instead:
https://github.com/Homebrew/homebrew-versions
2.3.0 git checkout 7ed33a1 Library/Formula/hadoop.rb
2.2.0 git checkout 61dcbbd Library/Formula/hadoop.rb
1.2.1 git checkout a49c2fa Library/Formula/hadoop.rb
1.1.2 git checkout d133e18 Library/Formula/hadoop.rb
1.1.1 git checkout 6f15c8f Library/Formula/hadoop.rb
1.0.4 git checkout ce2f7e1 Library/Formula/hadoop.rb
1.0.3 git checkout 3c5ca25 Library/Formula/hadoop.rb
1.0.1 git checkout 81353a3 Library/Formula/hadoop.rb
1.0.0 git checkout 6eebea9 Library/Formula/hadoop.rb

0.20.2 git checkout d0efd9e Library/Formula/hadoop.rb
0.20.1 git checkout e5869fe Library/Formula/hadoop.rb

然后

 cd /usr/local/Library/Formula/ 

接着更新ruby文件：

git checkout 61dcbbd hadoop.rb

最后安装直接执行

brew install hadoop

返回：
