    Default Hadoop Transformation Job Executor: Null Pointer Exception

    Any ideas on what the error below indicates would be very helpful.
    Let me know if I can provide any additional info.
    I am using Hadoop 0.20.2+737.

    Code:

    Amici,

    Maybe you could attach your job and transformations ?

    Default

    Amici,

    That error was from an internal developer build and has since been fixed. It happens a mapper is allocated and not used.

    Thanks for the feedback.
