> Project: Apache AsterixDB
> Issue Type: Bug
> Reporter: Yingyi Bu
> Assignee: Abdullah Alamoudi
> Priority: Critical
> Attachments: cc.log, test_nc1.log, test_nc2.log
>
>
> I created a feeds and it works fine.
> However, after I restart the instance, I connect the feeds again to the same
> dataset. I feed one tuple into the feeds. Then, the dataset becomes not
> query-able with a NPE.
> Logs are attached.
