hadoop - 配置单元不与 Ambari 一起使用 HDP

Question

我已经用 Ambari 2.6.1 安装了 HDP。它主要自动完成所有操作，但 Hive 无法正常启动。

我在某处看到一个帖子，我删除了 pid 并终止了进程，希望我能重新启动它并且它能正常工作，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 得到的错误。

1.Hive Metastore:

Answer 1

这个问题有以下三个不同的问题

1. Hiveserver2 警报:以下错误指示端口 10000在 machine2.ambari.local无法访问，或者没有进程 (HiveServer2) 在端口 10000 上运行或一些代理问题。

   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: Connection refused(连接被拒绝)

2. 心跳丢失:问题中提到“机器上的心跳丢失”，这可能是因为 ambari-agent进程不再在通知心跳丢失的主机上运行。

3. 删除pid杀掉进程后，默认不会自动重启。
