Feeds tutorial is outdated or doesn't work

[GoogleCodeExporter]

I can't seem to create a vanilla feed, using the push-based twitter adapter, as 
is in the new tutorial in the docs.

I create the feed using the specified syntax

     create feed TwitterFeed if not exists using "push_twitter"
    (("type-name"="Tweet"),("location"="US"));

And a dataset that is of the right type

    create dataset Tweets(Tweet) primary key id;

But trying to connect it fails

    connect feed TwitterFeed to dataset Tweets;

With this error, which doesn't really make a lot of sense considering this 
adapter is baked in

    unable to create adapter java.lang.ClassNotFoundException: push_twitter [AlgebricksException]

And what is more bewildering, is that if I drop, create, and reconect the feed- 
it doesn't throw an exception any longer, but it doesn't actually work either. 
All that appears in the logs is this:

I was planning to try this feed feature (after testing the fuzzy-query 
feature).  After Ian's pass, I can have mine.
