Description

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.
