Hello All,
I am using IDEA 15.0.4 to debug a scala program. It is strange to me that the
results were different when I debug or run the program. The differences can be
seen in the attached filed run.jpg and debug.jpg. The code lines of the scala
program are shown below.
Thank you all

I am new to spark. I use IDEA ver 14.0.3 to debug spark recently.It is strange

Hello Felix,
No, this line isn't the one that is triggering the execution of the function,
the count does that, unless
ow me the line it is which triggeres the
evaluation.
Thanks you very much

Hi Felix,
Are sure your n is greater than 0?

You can call a count in the ide just to debug, or you can wait until it reaches
the code, so you can debug.
Some ides provide you a

Hello Felix,
Spark functions run lazy, and that's why it doesn't stop in those breakpoints.
They will be executed only when you call some metho
Hi all,
I am newbie to spark. I am learning spark by debugging the spark code. It is
strange to me that it does not stop at breakpoints which is in an anonymous
function, it is normal in ordianry function, though. It that normal. How to
obverse variables in an anonymous function.
