在 Ambari 上安装 HDFS 客户端时出现以下错误。已经多次重置服务器，但仍然无法解决。知道如何解决吗？

标准错误：

yum -y erase hdp-select

如果您已多次安装，可能无法清除某些软件包。

要删除所有 HDP 软件包并开始全新安装，请擦除 hdp-select。

如果这没有帮助，请从/usr/hdp删除此目录中删除所有版本，如果它包含多个版本hdp

删除所有已安装的软件包，例如hadoop,hdfs,zookeeper etc.

yum remove zookeeper* hadoop* hdp* zookeeper*

这是一个链接到/etc/hadoop/conf的软链接

我跑

python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent --skip=users

运行后，它会删除/etc/hadoop/conf

但是，重新安装不会重新创建它。

因此，您可能必须自己创建所有 conf 文件。希望有人可以修补它。

我遇到了同样的问题：我在 Centos 7 上使用 HDP 2.3.2。

第一个问题： 一些 conf 文件指向 /etc//conf 目录（与它们应该的相同） 但是，/etc//conf 指向另一个 conf 目录，这导致了无限循环。

我能够通过删除 /etc//conf 符号链接并创建目录来解决这个问题

第二个问题 如果您运行 python 脚本来清理安装并重新开始，则不会重新创建几个目录，例如 hadoop-client 目录。这会导致准确的错误消息。此外，此清理脚本效果不佳，因为它不会清理多个用户和目录。你必须 userdel 和 groupdel。

更新：这似乎是 HDP 2.3.2 的问题。在 HDP 2.3.4 中，我不再遇到这个问题。

在失败的主机上创建/usr/hdp/current/hadoop-client/conf应该可以解决问题。
