ERROR VertexFailedFast. Vertex failure triggered quick job abort

Question

I am running a Data Lake - Analytics job and I get the below error

ERROR VertexFailedFast. Vertex failure triggered quick job abort. Vertex failed: SV1_Extract[0][0] with error: Vertex user code error. DESCRIPTION Vertex failed with a fail-fast error

Does anybody know why this happens? 

Answer 1

• This error occurred as your extraction has been failed.

• Basically, whenever you use built-in extraction, you will fail to typecast data and you have an incorrect number of columns.

• If you use a user-defined extractor, some kind of C# runtime error occurs which is generated by the user.
