--------------------------------------------
Assignee: Xikui Wang
> Inconsistent behavior w.r.t. connecting/disconnecting feed to a non-existing
> dataset
> ------------------------------------------------------------------------------------
>
> Key: ASTERIXDB-1860
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-1860
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: Feeds
> Reporter: Chen Luo
> Assignee: Xikui Wang
> Priority: Minor
>
> Connecting a feed to a non-existing dataset (whose name is 'unknown_dataset')
> is successful, and the system shows the message:
> {code}Success: Query Complete.{code}
> However, disconnecting this feed to this dataset is rejected with error
> message: {code}Unknown target dataset :unknown_dataset
> [CompilationException].{code}
> Then, connecting this feed to the dataset again gives: {code}FeedTweetFeed is
> already connected dataset unknown_dataset [AlgebricksException].{code}
> Thus, it seems once a feed is connected to a non-existing dataset, it cannot
> be disconnected from it.
> Steps to reproduce:
> # create a feed named Feed1;
> # connect Feed1 to a non-existing dataset, e.g., unknown_dataset:
> {code}
> connect feed Feed1 to dataset unknown_dataset;
> {code}
> Now Feed1 is successfully connected to unknown_dataset.
> # disconnect Feed1 from unknown_dataset:
> {code}
> disconnect feed Feed1 from dataset unknown_dataset;
> {code}
> This command is rejected because unknown_dataset is not existing.
> # connect Feed1 to unknown_dataset again:
> {code}
> connect feed Feed1 to dataset unknown_dataset;
> {code}
> The system shows Feed1 is already connected to unknown_dataset.
