Error compiling U-SQL project (E_CQO_SYSTEM_INTERNAL_ERROR)


  • Hi,

    I am trying to compile a simple U-SQL script:

    @input =
        EXTRACT First_Name string,
                Last_Name string
        FROM "/sample_input.csv"
        USING Extractors.Csv();
    OUTPUT @input
    TO "/sample_output.csv"
    USING Outputters.Csv();

    And I face this error:

    Severity Code Description
    Error E_CQO_SYSTEM_INTERNAL_ERROR: Internal optimizer error.
    Please contact support.

    Could you please help out here?  I tried searching for this error in MSDN and each time there is a different fix (enclosing queries in parantheses, no space in file names, etc.).  What could be possibly going wrong with the most simple script pasted above?

  • There is no problem with the script. I executed using your script and it is running perfectly fine. Please check the screenshots below

    Can you please paste a sample of your "/sample_input.csv" file?
