我正在尝试使用ambari1.7.0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）使ambari agent守护进程在代理节点上运行之后，我可以注册目标主机。
但是，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 resource_management.libraries.functions.dfs_datanode_helper import handle_dfs_data_dir
ImportError: No module named dfs_datanode_helper

ambari-agent.log包含以下内容：

问：为什么即使我选择了hdp2.2，也要安装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：hdp-2.2 hdp-utils-1.1.0.20 updates-ambari-1.7.0 ambari-1.x
