3. Occasionally, after executing the same query after it failed, I see an error
on failing to create 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)

To reproduce:
1. Single drillbit
2. Configuration:
DRILL_MAX_DIRECT_MEMORY="8G"
DRILL_HEAP="4G"
3. Dataset: tpcds100 parquet
4. Run query:
{code}
select
sum(ss_quantity) over(partition by ss_store_sk order by ss_sold_date_sk)
from store_sales;
{code}
> Query with window function and sort below that spills to disk runs out of
