We will need to
- get actor information from the actor table via cuc_actor
- get comment information from the comment table via cuc_comment_id
By the time the source table is starting to deprecate the old cuc_user, cuc_user_text, cuc_comment fields, we may want to just move this from sqoop to Spark. But as a stop-gap, we will add some patches here that we can use if we're not ready and the columns are dropped.
