【问题描述】：

我正在尝试向我的 Ambari 集群添加更多主机，运行 HDP 2.4，但 Metrics Monitor 似乎没有正确安装，所有其他服务都正常启动。

以下是我尝试在其中一台新主机上启动 Metrics Monitor 时得到的输出。

这是/var/log/ambari-metrics-monitor/ambari-metrics-monitor.out的输出

psutil binaries need to be built by running, psutil/build.py manually or by running a, mvn clean package, command.

我尝试进入该目录并运行sudo python psutil/build.py，以及运行sudo make。两者都不起作用。

任何想法都会很棒！

【解决方案1】：

这是您的 python 环境的问题，它已经以某种方式损坏（很可能使用 sudo pip install <package>，同时使用 sudo 和 pip 有时会导致此问题）。在此SO question 上有有关如何解决此问题的详细信息。修复 python 问题后，您应该能够通过 Ambari 重试主机添加。
