[jira] [Commented] (DRILL-1327) Any subsequent query may hung in
sqlline after you cancel one query in the same session

Jason Altekruse commented on DRILL-1327:
----------------------------------------
I was unable to re-produce this on my machine. Are you running sqlline in local mode? Could you possibly try to re-produce this using a build of the latest master?

> This is another issue related to DRILL-1326.
> If we cancel a query in sqlline, subsequent query may hung.
> I can reproduce it almost every time.
> How to reproduce:
> 1. Logon sqlline, run below SQL:
> {code}
> select *
> from cp.`employee.json` a, cp.`employee.json` b
> where a.position_id=b.position_id ;
> {code}
> 2. When it is printing the results for about 3 seconds, type "ctrl-c" to stop it.
> 3. Then any subsequent query will hung.

> In the end, we have "ctrl-z" and "kill -9 %1" to exit the sqlline.
> After that, the SQL become "Running Queries" forever.
> We need to fix this because it looks like the sqlline is not stable.
