Chen Li commented on ASTERIXDB-1074:
------------------------------------
I had a pass on the feed tutorial. I believe it needs more work to be useable.
A lot of places seem to be copied from a paper, with missing references "Table
1" and "Figure 9". Also several places are not consistent, and don't work.
We need someone to look into all the details to make them work and consistent.
I can guide in the process. I already marked some places on a printout.

> 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:
> 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
