Zeppelin段落中可能会看到一些错误输出吗? [英] Is it possible to see some error output in Zeppelin paragraphs?

问题描述

我有一个Zeppelin安装程序，并且正在使用Spark解释器.但是，如果遇到语法错误或运行时错误，除错误"一词外，我找不到其他详细信息.

I have a Zeppelin installation and am using the Spark interpreter. However, if I have a syntax or runtime error, I cannot find any details except the "Error" word.

例如，我有以下代码:

我只在右上角看到错误"字样.

And I only see the "ERROR" word in the top-right corner.

在我自己的计算机上，scala会打印以下内容:

In my own computer, scala would instead print something like:

$ scala example.sc
./example.sc:1: error: recursive value a needs type
val a = this is an error
             ^
.example.sc:1: error: not found: value an
val a = this is an error
                ^
two errors found

我正在使用版本0.7.3.

I'm using version 0.7.3.

推荐答案

您需要在Interpreter选项卡中将zeppelin.spark.printREPLOutput设置为true.

You will need to set zeppelin.spark.printREPLOutput to true in the Interpreter tab.

其缺点是它将显示REPL显示的所有内容.

The downfall of this is that it will show everything that REPL shows.
