Apache zeppelin教程，错误“未找到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，我不能使用％sql解释器.它将输出"sql interpreter not found".但是spark命令以及%md和%sh都可以正常工作.

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

我有相同的错误.问题是火花解释器被取消选择.在教程页面顶部，打开齿轮图标，并确保"spark％spark ..."为 blue ，然后单击保存".

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.

此处的UI有点令人困惑.默认情况下，所有解释器都处于选中状态(蓝色).您只需要单击保存"

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