Few user_id data is missing in output table from lookup.

    The behavior you are describing is possible when there is a delay or a time window defined on the lookup table. meaning that the data in the lookup table may yet or already not fit into the tie window, hence it will not appear in the joins. So basically while the data does appear in the lookup table, it just doesn't match your join time criteria.
