FYI we're almost done converting the legacy hadoop wiki over to the new zk tlp cwiki. Any/all pages should be moved over, if not let us know, for example the faq: https://cwiki.apache.org/confluence/display/ZOOKEEPER/FAQ
I do notice that's missing the attachment as well. Unfortunately spammers hit the wiki pages hard, as a result [email protected] had turned off attachments. Not sure the status of cwiki. Ben, what's the status on this? Is there a way we can update this? (iirc isn't that diagram also in the docs? perhaps we could re-attach from there?)
