在 hadoop 2.7.3 错误上安装 oozie 4.3.0

Question

当我尝试创建 oozie 发行版时，我正在尝试在 hadoop 2.7.3 上安装 oozie 4.3.0。它因以下错误消息而失败。

同时检查 setting.xml 代理标签，它被正确提及无法弄清楚是什么问题。

 <proxy>
  <id>myproxy</id>
  <active>true</active>
  <protocol>http</protocol>
  <username>xxxx</username>
  <password>xxxx</password>
  <host>xxxx</host>
  <port>xxxx</port>
  <nonProxyHosts></nonProxyHosts>
</proxy>

Answer 1

我已经更新了 /usr/share/maven/conf/settings.xml 文件中的代理设置，而不是 ${HOME}/.m2/settings.xml，它解决了这个问题。
