minor - A simple list will do here. Also consider using Guava collections.
> Drill not deleting spooling files

> Key: DRILL-2100
> URL: https://issues.apache.org/jira/browse/DRILL-2100
> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Relational Operators
> Affects Versions: 0.8.0
> Reporter: Abhishek Girish
> Assignee: Deneche A. Hakim
> Fix For: 1.7.0
>
>
> Currently, after forcing queries to use an external sort by switching off
> hash join/agg causes spill-to-disk files accumulating.
> This causes issues with disk space availability when the spill is configured
> to be on the local file system (/tmp/drill). Also not optimal when configured
> to use DFS (custom).
> Drill must clean up all temporary files created after a query completes or
> after a drillbit restart.
