我已经使用Ambari 2.6.1安装了HDP。它主要是自动完成所有操作，但是Hive无法正常启动。
我在某个地方看到了一个帖子，我删除了pid并杀死了这个进程，希望我能重新启动它，它会工作但现在它显示机器上的心跳丢失。
请指导我该怎么做？
我列出了我从ambari获得的错误。

答案 0 :(得分：0)
此问题中存在以下三个不同的问题
Hiveserver2警告：以下错误表明10000上的端口machine2.ambari.local无法访问，或者端口10000上没有正在运行的进程（HiveServer2）或某些代理问题。
错误：无法使用JDBC Uri打开客户端传输：jdbc：hive2：//machine2.ambari.local：10000 /; transportMode = binary：java.net.ConnectException：连接被拒绝（连接被拒绝）
< / LI>心跳丢失：有问题提到“心跳在机器上丢失”，这可能是因为ambari-agent进程不再在主机上运行，通知心跳丢失。
删除pid并终止进程后，默认情况下不会自动重启。
