[jira] [Updated] (ASTERIXDB-1302) Deadlock while trying to drop feed dataverse

["Ildar Absalyamov (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ASTERIXDB-1302?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ildar Absalyamov updated ASTERIXDB-1302:
----------------------------------------
    Description: 
Connected feed deadlocks :
{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;
{noformat} 
Any modification operation on dataset\dataverse such as drop would result in a deadlock
{noformat} 
drop dataverse experiments;
{noformat} 
The correct behavior would be to give an error message to the user, notifying that the feed should be disconnected first, or allowing to drop dataverse, while managing locks correctly
