在ambari2.7.4向导上安装hadoop3.1.4时遇到了一个奇怪的问题。作为os/environment，我们有一个Suse12Linux（已经设置好了），并且在一个代理服务器后面——我要指出的是。可以访问hdp存储库：
http://public-repo-1.hortonworks.com/hdp-utils-1.1.0.22/repos/sles12/
http://public-repo-1.hortonworks.com/hdp-gpl/sles12/3.x/updates/3.1.4.0
http://public-repo-1.hortonworks.com/hdp/sles12/3.x/updates/3.1.4.0/
在将数据库（它已经存在于postgres上，有一个hivedb和一个hiveuser）连接到hivemetastore的步骤中，我们在“check connection”按钮失败（postgres和ambari在同一个主机上）。我们还为ambari甚至在suse代理文件中设置了“no proxy”设置。
据我们所知，错误消息是，ambari无法在运行的同一台服务器上访问他自己的Resources文件夹？？任何帮助都将不胜感激：）
