Failure looks legitimate from customer point of view (granted that we know that we can run out of memory in some cases)
However, there are couple of problems with this scenario:
1. It looks like we are running out of memory during disk based sort

2. The same sort running by itself and spilling to disk finishes successfully.
3. There is an indication in drillbit.log that memory leak has occurred.

3. Ocasionally, after executing the same query after it failed, I see an error on failing to created a spill directory even though I have enough disk space in my spill directory that is configured to be on a local file system.
(remember, sort by itself runs fine)
