All the attachments on the wiki disappeared a while ago. I noticed it recently on my design doc for views. I think probably somebody disabled attachment upload due to spam, and this made the existing attachments inaccessible as well. Probably need to open an INFRA ticket in Apache JIRA.

I was looking for the Hive architecture diagram on this page http://wiki.apache.org/hadoop/Hive/Design . The pdf link doesnt seem to work for me as well. It would be a great help if someone could direct me to this information.

I put that when I thought we were going to actively move to xdocs. You an remove that if you like. As i said in a thread before the problem with the wiki is that no one actively updates it. Example: http://wiki.apache.org/hadoop/Hive/LanguageManual/Select oopse: Really what about "in support"... https://issues.apache.org/jira/browse/HIVE-801 Which is why I hold the option that all patches except bug fixes should probably come with xdocs, People are free to disagree.
