U-SQL脚本调试错误

Question

While debugging the U-SQL script, I am facing the debug issue of ScopeEngine. "ScopeEngine.pdb file contains the debug information required to find the source for the module ScopeEngine.dl"

Is there any way to resolve this issue?

Answer 1

You should be safe to ignore ScopeEngine.pdb as it is not supposed to be debuggable in your case. It's a native DLL.

Answer 2

Although you don't specify, I assume you are debugging a local run of your job in VS (rather than debugging a failed vertex). In this scenario you can see failure anywhere in the stack but the intent is to let you debug user code you wrote (UDFs, included assembly). There is a whole lot of runtime stack that you cannot debug in.

If you are seeing a failure inside the stack you should refer to the error message of course. If it says internal error you can raise a ticket with Azure.

Answer 3

For your local machine, you can try to go to the VS debugging options and:

• Uncheck Enable just my code
• Check Suppress JIT optimization on module load
