我正试图让配置单元LLAP在我的服务器上运行。
到目前为止，我的设置是：Hadoop 3.31、tez 0.9.2、hive 3.1.2、zookeper 3.7.0，所有这些都来自tar文件。
泰兹的蜂巢正在工作。选择返回预期结果。
现在我想让LLAP运行，所以我设置了配置文件，并用生成了脚本
hive --service llap --name llap0 --instances 2 --size 6g --loglevel DEBUG --cache 2g --executors 2
纱线应用程序已成功启动，但在应用程序日志中显示：

所以服务正在启动容器，但我无法连接到它。
是否缺少任何选项，或者在哪里设置端口映射？
问题的直接解决方案：在Hadoop 上设置LLAP
在这里，它讨论了如何在Hadoop集群上设置HiveLLAP来消除这些问题。
