Subject [jira] [Commented] (DRILL-2100) Drill not deleting spooling files
Date Thu, 26 Mar 2015 03:20:53 GMT

Steven Phillips commented on DRILL-2100:
----------------------------------------

Are you seeing this happen in all cases, or just when a query fails or is canceled?

I believe the code does currently clean up the files, but there may be some cases where it
does not.

>          Components: Execution - Relational Operators
>    Affects Versions: 0.8.0

> 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.
