> Feeds tutorial is outdated or doesn't work

>                 Key: ASTERIXDB-1074
>                 URL:
>             Project: Apache AsterixDB
>          Issue Type: Bug
>          Components: AsterixDB
>            Reporter: Ian Maxon

>            Priority: Critical
> 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: 
> Aug 11, 2015 12:20:34 PM edu.uci.ics.asterix.aql.translator.AqlTranslator getFeedConnectionRequest
> INFO: Feed joint feeds.TwitterFeed: [SOURCE_FEED_INTAKE_STAGE][CREATED] is available!
need not apply any further computation
