------------------------------------
Summary: Feeds tutorial is outdated or doesn't work
Key: ASTERIXDB-1074
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1074
Project: Apache AsterixDB
Issue Type: Bug
Components: AsterixDB
Reporter: Ian Maxon
Priority: Blocker
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
