    two more things:
    1. this function is only used once, so I think there is no need to place it in `CommonUtil`.
    2. is `distinct` case-sensitive or not?

    Hi @xuchuanyin ,
    Thank you for the comments. Have changed to use flatten function.
    1. Put in CommonUtil not only for reusing but also keep code in one style and put similar function in one place.
    2. distinct is case sensitive
