如何使用 Ambari UI 配置 Analytics Engine 使用 Hive LLAP？

Question

IAE 是否支持 Hive LLAP 功能？如果是，如何使用 Ambari 启用它 UI?

我尝试基于 tutorial from Hortonworks 启用，但出现错误：

我已按照 https://hortonworks.com/tutorial/interactive-sql-on-hadoop-with-hive-llap/ 中描述的步骤进行操作，并且有效。

我认为，您应该注意的是按照建议更改 YARN 内存，过程中没有的一件事是启用 "Pre-emption" YARN 功能。
