             Summary: Drop temporary dataset throws NullPtrException when an unrelated feed adapter was set up before
                 Key: ASTERIXDB-1262
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1262
             Project: Apache AsterixDB
          Issue Type: Bug
          Components: Feeds
            Reporter: Jianfeng Jia
            Assignee: Abdullah Alamoudi


Hi, 
Here is the step to reproduce the problem:

* ddl
{code}
drop dataverse test if exists;
create dataverse test;
use dataverse test;

create type t1 as open{ 
    id: int64,
    name: string
}

create dataset ds1 (t1) primary key id;

create feed fd2 using socket_adapter
(
    ("sockets"="nc2:10001"),
    ("address-type"="nc"),
    ("type-name"="t1"),
    ("format"="adm"),
    ("duration"="1200")
);
set wait-for-completion-feed "false";
connect feed fd2 to dataset ds1 using policy AdvancedFT_Discard;
{code}

* Create and drop an unrelated temporary dataset
{code}
create temporary dataset tmp_tweets(t1) primary key id; 
drop dataset tmp_tweets
{code}
Then the expection appears as below
* Exceptions:
{code}

The drop statement will work fine if we didn't set up the feed adapter.
