Question

我尝试使用Ambari 1.7.0设置6节点HDP 2.2群集。在黑客攻击之后（通过向ambari-agent / ambari-enh添加＆p 39;导出PYTHON = / usr / bin / python2.6＆＃39）以使代理节点上运行ambari-agent守护程序，我就是这样做的。我能够注册目标主机。

然而，我在“部署”期间遇到了一个可怕的问题。步。虽然我选择了HDP 2.2堆栈，但似乎仍然选择了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：

  'stdout': '2015-02-06 00:11:47,687 - Error while executing command

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

问题：即使我选择了HDP 2.2，为什么还要安装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

这是预期的行为。 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，它也继承自2.0.6版本。

这里定义的是：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根本就没有运行。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。

HortonWorks Ambari 1.7.0选择了错误的HDP堆栈
