Apache zeppelin 教程，错误“找不到 sql 解释器" [英] Apache zeppelin tutorial, error "sql interpreter not found"

问题描述

在Zeppelin 教程"笔记本中，我无法使用 %sql 解释器.它将输出sql interpreter not found".但是 spark 命令工作正常，以及 %md 和 %sh.

In the "Zeppelin tutorial" notebook, I can't use the %sql interpreter. It will output "sql interpreter not found". But the spark commands work fine, as well as %md and %sh.

这是日志:

推荐答案

我遇到了同样的错误.问题是取消选择了 spark 解释器.在教程页面顶部，打开齿轮图标并确保spark %spark..."为蓝色，然后点击保存.

I had the same error. The problem was that the spark interpreter was deselected. At the top of the tutorial page, open the gear icon and make sure "spark %spark..." is blue and click save.

这里的用户界面有点混乱.默认情况下，所有解释器都被选中(蓝色).你只需要点击保存"

The UI is a bit confusing here. All interpreters are selected (blue) by default. You just have to click "save"
