Description
Query was cancelled during external sort.
Here is what happened:
1. Query got stuck in CANCELLATION_REQUESTED mode: ( queryid = 2967b65e-ea42-a736-9f5d-3513914ada88 )
2. On a forman node 6:0 (executing merge join) fragment kept running forever (see stack below)

After server was restarted:
1. Query profile was never saved in profiles directory as if it never ran
2. I saved JSON profile off the screen just before that, can be found here: 2967b65e-ea42-a736-9f5d-3513914ada88.sys.drill
3. drillbit.log showed leak :

- I was running with Amit's patch for fix
DRILL-4190: https://github.com/amithadke/drill/tree/DRILL-4190
- Not sure if this is reproducible case, I will try. Hope there is enough information to give it a clue on what happened.
