在将主机添加到群集之前手动添加ambari-hdp-1.repo和yum-installing hdp-select会显示相同的错误消息，只是被截断为以下部分，这进一步加强了这一点：此处显示的是stdout / err。
运行时

在ambari服务器节点上，我可以看到命令运行。
看看钩子脚本试图运行/访问什么，

注意有ls: cannot access /var/lib/ambari-agent/data/structured-out-632.json: No such file or directory。不过，不确定这是否正常。
任何人都知道这是什么原因或导致任何调试提示吗？
UPDATE 01 ：
在错误跟踪中有问题的最后一行附近添加一些日志打印行。 File "/usr/lib/ambari-agent/lib/resource_management/libraries/functions/stack_select.py", line 147, in get_supported_packages，我打印代码和标准输出：

ambari-python-wrap: can't open file '/usr/bin/hdp-select': [Errno 2] No such file or directory
那到底是什么？它希望hdp-select已经存在，但是如果我事先手动安装该二进制文件，则ambari add-host UI会抱怨。当我手动安装它（使用与其他现有群集节点中相同的存储库文件）时，我看到的只是...

因此，似乎无法创建hive用户（尽管在此之前创建yarn-ats用户似乎没有问题）
答案 0 :(得分：0)
在让步并尝试自己手动创建配置单元用户之后，我看到了
[root@airflowetl ~]# useradd -g hadoop -s /bin/bash hive
useradd: user 'hive' already exists
[root@airflowetl ~]# cat /etc/passwd | grep hive
<nothing>
[root@airflowetl ~]# id hive
uid=379022825(hive) gid=379000513(domain users) groups=379000513(domain users)
该现有用户的uid看起来像这样并且不在/etc/passwd文件中这一事实使我认为已有一些现有Active Directory用户（此客户端节点通过已安装的SSSD与之同步）。蜂巢的名字。检查我们的AD用户，事实证明这是事实。
暂时stopping the SSSD service以停止与AD（service sssd stop）的同步（因为不确定是否可以让服务器忽略单个用户的AD同步），然后重新运行Ambari中添加的客户端主机为我解决了这个问题。
