Description

Upon canceling a query all drillbits crash.

> SELECT RANK() OVER (PARTITION BY ss.ss_store_sk ORDER BY ss.ss_store_sk), AVG(ss_ext_discount_amt) OVER (PARTITION BY ss.ss_store_sk ORDER BY ss.ss_store_sk) FROM store_sales ss WHERE ss.ss_store_sk is not NULL LIMIT 20;
[Cancel]

Upon reissuing a query, I see an error with connection. Upon inspection, all drillbits were down. There was a JVM crash.

> select * from store_sales limit 1;
Error: CONNECTION ERROR: Connection /10.10.120.101:55788 <--> /10.10.120.110:31010 (user client) closed unexpectedly.
