Is it possible to see some error output in Zeppelin paragraphs?

问题

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.

For example, I have this code:

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

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

I'm using version 0.7.3.

回答1:

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

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