----------------------------------
Summary: External sort does not handle its own UserExceptions
Key: DRILL-5058
URL: https://issues.apache.org/jira/browse/DRILL-5058
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.8.0
Reporter: Paul Rogers
Assignee: Paul Rogers
The external sort throws a {{UserException}} in a variety of conditions: error
during spilling, on out-of-memory on SV2 allocation, and on a schema change.
However, except for the schema change, the external sort does not *handle* the
exceptions that it throws. In part this is because {{UserException}} is
unchecked, so the code is not obligated to handle it.
The fix is to add a catch for {{UserException}} to the block of catches in
{{innerNext()}}.
