hadoop - 服务器安装 hdfs 客户端失败

Question

我在 Ambari 上安装 HDFS 客户端时收到以下错误。服务器重置了好几次，还是解决不了。知道如何解决这个问题吗？

标准错误:

Traceback (most recent call last):

Answer 1

这是一个链接到/etc/hadoop/conf的软链接(soft link)

我跑

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

运行后，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的 conf 文件。 希望有人能修补它。
