使用自制软件安装hadoop时出错

Question

我正在尝试在我的Mac上本地设置hadoop,但在尝试brew install hadoop时遇到以下错误:

$ brew install hadoop
==> Downloading http://www.apache.org/dyn/closer.cgi?path=hadoop/core/hadoop-1.1.2/hadoop-1.1.2.tar.gz
==> Best Mirror http://apache.mirrors.pair.com/hadoop/core/hadoop-1.1.2/hadoop-1.1.2.tar.gz

curl: (22) The requested URL returned error: 404
Error: Download failed: http://www.apache.org/dyn/closer.cgi?path=hadoop/core/hadoop-1.1.2/hadoop-1.1.2.tar.gz

任何想法我应该做什么？

Answer 1

你必须先做brew update.它指的是错误的版本,但现在似乎已经修复了.

Answer 2

似乎Homebrew公式Hadoop已经过时了，它指向1.1.2而不是1.2.1。在 Homebrew 的人员修复该错误之前，您可以执行以下步骤来安装 Hadoop 1.1.2：

1. 从http://archive.apache.org/dist/hadoop/core/hadoop-1.1.2/hadoop-1.1.2.tar.gz手动下载版本 1.1.2到计算机中的任何文件夹
2. 然后将文件移动hadoop-1.1.2.tar.gz到 homebrew 的临时文件夹，如果你之前没有更改过，它应该位于/Library/Caches/Homebrew

3. 最后就可以使用Homebrew安装Hadoop了，现在brew会发现文件已经下载好了，会继续安装，如下：

   $ brew install hadoop
   ==> Downloading http://www.apache.org/dyn/closer.cgi?path=hadoop/core/hadoop-1.1.2/hadoop-1.1.2.tar.
   Already downloaded: /Library/Caches/Homebrew/hadoop-1.1.2.tar.gz
   ==> Caveats
   In Hadoop's config file:
     /usr/local/Cellar/hadoop/1.1.2/libexec/conf/hadoop-env.sh
   $JAVA_HOME has been set to be the output of:
     /usr/libexec/java_home
   ==> Summary
     /usr/local/Cellar/hadoop/1.1.2: 271 files, 78M, built in 2 seconds
