-----------------------------------

             Summary: 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
            Priority: Minor


Connecting a feed to a non-existing dataset (whose name is 'unknown_dataset') is successful,
and the system shows the message: "Success: Query Complete".
However, disconnecting this feed to this dataset is rejected with error message: "Unknown
target dataset :unknown_dataset [CompilationException]".
Then, connecting this feed to the dataset again gives: "FeedTweetFeed is already connected
dataset unknown_dataset [AlgebricksException]".

Thus, it seems once a feed is connected to a non-existing dataset, it cannot be disconnected
from it.

Steps to reproduce:
1. create a feed named Feed1;

2. connect Feed1 to a non-existing dataset, e.g., unknown_dataset:
"connect feed Feed1 to dataset unknown_dataset;"
Now Feed1 is successfully connected to unknown_dataset.

3. disconnect Feed1 from unknown_dataset:
"disconnect feed Feed1 from dataset unknown_dataset;"
This command is rejected because unknown_dataset is not existing.

4. connect Feed1 to unknown_dataset again:
"connect feed Feed1 to dataset unknown_dataset;"
The system shows Feed1 is already connected to unknown_dataset.
