Paul Rogers resolved DRILL-5055.
--------------------------------
Resolution: Fixed
> External Sort does not delete spill file if error occurs during close
> ---------------------------------------------------------------------
>
> Key: DRILL-5055
> URL: https://issues.apache.org/jira/browse/DRILL-5055
> Project: Apache Drill
> Issue Type: Sub-task
> Affects Versions: 1.8.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
>
> DRILL-3898 recently fixed a case in which disk space was exhausted during a
> spill event for the external sort. In this case, the call to close failed
> because close attempted to flush remaining buffered data, but that also
> failed due to out of space.
> While the fix works, the fix causes the partially-completed spill file to be
> left on disk. Consider this code in {{BatchGroup.close( )}}
> {code}
> if (outputStream != null) {
> outputStream.close();
> }
> ...
> if (fs != null && fs.exists(path)) {
> fs.delete(path, false);
> }
> {code}
> Notice that, if the output stream close fails, the spill file is not deleted.
> The fix is to put the delete in a finally block so that it is always deleted.
