Lin Wen commented on HAWQ-1530:
-------------------------------
Hi,
Do you have a detailed reproduce for this bug?
I want to reproduce it in my environment, is it a must to install Aqua Data
Studio?
Can we open multiple psql sessions and run some queries, etc, to reproduce it?
Thanks!

> Priority: Major

> Hi,
> When you perform a long running select statement on 2 hawq tables (join) from
> JDBC and illegally kill the JDBC client (CTRL ALT DEL) before completion of
> the query the 2 tables remained locked even when the query completes on the
> server.
> The lock is visible via PG_locks. One cannot kill the query via SELECT
> pg_terminate_backend(393937). The only way to get rid of it is to kill -9
> from linux or restart hawq but this can kill other things as well.
> The JDBC client I am using is Aqua Data Studio.
> I can provide exact steps to reproduce if required
> Thank you
> Grant
