Hi Jianhua, I think that all of the wiki attachments were removed in an effort to get rid of spam postings that had been flooding the wiki. I believe that the diagrams that originally appeared in the design document are also available in Liyin's Join Optimization presentation, which you can find on slideshare here: http://www.slideshare.net/aiolos127/join-optimization-in-hive
