Python 如何解决以下问题-服务器已超过3分钟未收到来自此主机的检测信号

Python 如何解决以下问题-服务器已超过3分钟未收到来自此主机的检测信号,python,hadoop,certificate,ambari,hdp,Python,Hadoop,Certificate,Ambari,Hdp,我们正在使用蓝图来安装ambari群集(主计算机+数据节点计算机) 在blueprint安装期间,我们看到集群中的一些机器丢失了心跳信号,从ambari可以看到以下消息 the server has not received a heartbeat from this host for more than 3 minutes 我在谷歌搜索更苗条的问题 但我只发现了以下几点 一个建议是 更新: client.threadpool.size.max=<number of cores>

我们正在使用蓝图来安装ambari群集(主计算机+数据节点计算机)

在blueprint安装期间,我们看到集群中的一些机器丢失了心跳信号,从ambari可以看到以下消息

the server has not received a heartbeat from this host for more than 3 minutes
我在谷歌搜索更苗条的问题

但我只发现了以下几点

一个建议是

更新:

client.threadpool.size.max=<number of cores>
我不确定上面的建议,或者这里有人能提出正确的解决方案

# Possible values are:
# 'enable' to ensure HTTPS certificate verification is enabled by default
# 'disable' to ensure HTTPS certificate verification is disabled by default
# 'platform_default' to delegate the decision to the redistributor providing this particular Python version
