      Description

      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:

      INFO: Feed joint feeds.TwitterFeed: [SOURCE_FEED_INTAKE_STAGE][CREATED] is available! need not apply any further computation
