问题似乎是
resource_management.core.exceptions.ExecutionFailed: Execution of 'usermod -G hadoop -g hadoop hive' returned 6. usermod: user 'hive' does not exist in /etc/passwd
原因
2019-11-25 13:07:57,659 - Modifying user hive
Error: Error: Unable to run the custom hook script ['/usr/bin/python', '/var/lib/ambari-agent/cache/stack-hooks/before-ANY/scripts/hook.py', 'ANY', '/var/lib/ambari-agent/data/command-632.json', '/var/lib/ambari-agent/cache/stack-hooks/before-ANY', '/var/lib/ambari-agent/data/structured-out-632.json', 'INFO', '/var/lib/ambari-agent/tmp', 'PROTOCOL_TLSv1_2', '']
这进一步得到加强，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，只是被截断到stdout / err部分显示在这里。
运行时

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

注意，存在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由此引起的任何调试提示吗？
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。当我手动安装它时（使用与其他现有群集节点相同的回购文件），我看到的只是...

因此似乎无法创建hive用户（即使在此之前创建yarn-ats用户似乎没有问题）
[仅仅屈服并尝试自己手动创建配置单元用户后，我看到
[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文件中的事实使我认为，已有一些现有的Active Directory用户（此客户端节点通过已安装的SSSD与之同步）已经具有名称蜂巢。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的同步（service sssd stop）（因为不确定是否可以让服务器忽略单个用户的AD同步），然后重新运行客户端主机，在Ambari中添加为我解决了这个问题。
