多行命令（导出 .csv）在 Apache Drill（网络界面）中不起作用

Question

我正在尝试使用 Apache Drill 导出 .csv 文件。 This other question 表示这是通过以下方式实现的：

use dfs.tmp; 
alter session set `store.format`='csv';
create table dfs.tmp.my_output as select * from cp.`employee.json`;

我在 Apache Drill Web 界面中尝试运行同时执行此块（包含三个命令），但出现以下错误。它以某种方式无法识别 ; 或不接受多个命令。

我也尝试过运行单独设置每一行，没有 ; 但这两个命令的更改没有持续存在（并且导出命令（第三个命令）退回到导出镶木地板文件（默认设置））。

如何在 Drill 中运行这个？

Drill Web-UI不支持在同一个查询页面中提交多个查询。请尝试使用 SqlLine 或在 Web 中提交-UI 一个一个

alter system set `store.format`='csv';

在系统级别设置store.format的查询，因为Web-UI默认不存储会话，然后提交以下查询

create table dfs.tmp.my_output as select * from cp.`employee.json`;

多行命令（导出 .csv）在 Apache Drill（网络界面）中不起作用

Multi line command (to export .csv) not working in Apache Drill (web interface)
