----------------------------------------
> Deadlock while trying to drop dataverse of disconnected feed
> ------------------------------------------------------------
>
> Key: ASTERIXDB-1302
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-1302
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: ING - Ingestion
> Reporter: Ildar Absalyamov
> Assignee: Abdullah Alamoudi
> Priority: Major
>
> Consider the following feed definition:
> {noformat}
> drop dataverse experiments if exists;
> create dataverse experiments;
> use dataverse experiments;
> create type TwitterUserType as closed {
> screen-name: string,
> lang: string,
> friends_count: int32,
> statuses_count: int32,
> name: string,
> followers_count: int32
> }
> create type TweetMessageType as closed {
> tweetid: int64,
> user: TwitterUserType,
> sender-location: point,
> send-time: datetime,
> referred-topics: {{ string }},
> message-text: string
> }
> create dataset Tweets(TweetMessageType) primary key tweetid;
> create feed TweetFeed using socket_adapter
> (
> ("sockets"="127.0.0.1:10001"),
> ("address-type"="IP"),
> ("type-name"="TweetMessageType"),
> ("format"="adm")
> );
> set wait-for-completion-feed "false";
> connect feed TweetFeed to dataset Tweets;
> disconnect feed TweetFeed from dataset Tweets;
> {noformat}
> Even after the feed is in disconnected state any modification operation on
> dataset\dataverse such as drop would result in a deadlock
> {noformat}
> drop dataverse experiments;
> {noformat}
