我正在尝试使用本教程在我的ec2示例上设置hadoop。当我遇到以下错误时,我正在尝试设置ambari服务器:

[root@ip-xxx-xxx-xxx-xxx ec2-user]# ambari-server setup
Using python  /usr/bin/python2.6
Setup ambari-server

    setup(options)
  File "/usr/sbin/ambari-server.py", line 2089, in setup
    retcode = configure_os_settings()
  File "/usr/sbin/ambari-server.py", line 1909, in configure_os_settings
    os_name = os_info[0].lower()
AttributeError: 'NoneType' object has no attribute 'lower'

我真的不知道这是怎么发生的,也不知道该怎么做来解决这个问题。有人知道我做错了什么吗?
编辑:我在网站上查看了代码,发现:

os_info = platform.linux_distribution(
    None, None, None, ['SuSE', 'redhat' ], 0
  )
  os_name = os_info[0].lower()

看来 platform.linux_distribution 是用它的参数创建一个数组并对其执行其他操作。我在文件中找不到函数的实现,并且有几个文件在同一个目录中,仍然不确定该怎么办。

tyu7yeag1#

我解决了问题,我去掉了3个 None 对象并移除2大小的数组,并使它们成为自己的参数。然而,现在Ambari正在引发另一个问题。
