Python HortonWorks Ambari 1.7.0选择了错误的HDP堆栈

我正在尝试使用Ambari 1.7.0设置一个6节点HDP2.2集群。经过黑客攻击（通过将'export PYTHON=/usr/bin/python2.6'添加到ambari-agent/ambari-enh）以使ambari-agent守护进程在代理节点上运行之后，我能够注册目标主机

然而，我在“部署”步骤中遇到了一个可怕的问题。虽然我选择了HDP2.2堆栈，但HDP2.0.6仍然被选中

Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/services/HDFS/package/scripts/datanode.py", line 21, in <module>
from hdfs_datanode import datanode
  File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/services/HDFS/package/scripts/hdfs_datanode.py", line 21, in <module>
from resource_management.libraries.functions.dfs_datanode_helper import handle_dfs_data_dir
ImportError: No module named dfs_datanode_helper

问题：即使我选择了HDP2.2，为什么还要安装HDP2.0.6

我的环境信息： CentOS 6.6、HortonWorks Ambari 1.7.0、HDP-2.2、HDP-UTILS-1.1

回购协议：

HDP-2.2 HDP-UTILS-1.1.0.20更新-ambari-1.7.0 ambari-1.x预期的行为。Ambari堆栈可以从以前的版本继承。因此，在您的例子中，堆栈2.2的HDFS继承自堆栈版本2.1，后者也继承自版本2.0.6

这是在这里定义的：

现在，回到真正的问题上来，Ganglia根本没有运行。您看到的错误是在Ganglia服务的状态检查中引发的。我会从那里开始
