python - HortonWorks Ambari 1.7.0选择错误的HDP堆栈

我正在尝试使用Ambari 1.7.0设置6节点HDP 2.2集群。受到黑客攻击(通过将“export PYTHON = / usr / bin / python2.6”添加到ambari-agent / ambari-enh)以使ambari-agent守护程序在代理节点上运行之后，我能够注册目标主机。

但是，在“部署”步骤中，我遇到了一个可怕的问题。看来，尽管我选择了HDP 2.2堆栈，但仍选择了HDP 2.0.6。

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

ambari-agent.log包含以下内容:

          raise ComponentIsNotRunning()\nComponentIsNotRunning', 'exitcode': 1}

问题:即使选择了HDP 2.2，为什么仍要安装HDP 2.0.6？

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更新-ambari-1.7.0 ambari-1.x

最佳答案

那是预期的行为。 Ambari Stacks可以继承以前的版本。因此，在您的情况下，对于Stack 2.2，HDFS继承自Stack版本2.1，而后者又继承自版本2.0.6。

在这里定义:https://github.com/apache/ambari/blob/release-1.7.0/ambari-server/src/main/resources/stacks/HDP/2.2/metainfo.xml

现在，回到真正的问题，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。我将从这里开始。
