我们有ambari集群，HDP版本– 2.6.4和ambari版本– 2.6.1
集群中所有计算机上的ambari代理都存在严重问题！
例如，让我们承担计算机–数据节点计算机
在这台机器上，我们多次松动心跳（其平均代理已停止与ambari服务器通信），因此，作为解决方法，我们重新启动了ambari代理，并解决了此问题， 但是它一次又一次地返回
有时候，我们从ambari代理日志中看到正在使用的端口，因此我们杀死了PID并重新启动ambari代理（我们从netstat和端口号捕获PID） 但是这种行为会返回很多次
让我们总结一下情况–看来这可能是网络问题或某些中断，这些中断或中断了ambari代理与ambari服务器之间的连接，但我们没有解决方案，我们不确定这一点
请告知如何找到根本原因？
从日志中，我们可以看到以下内容：
