---------------------------------------------
Summary: Have cancel() cause "query canceled" rather than just
"ResultSet closed"
Key: DRILL-2884
URL: https://issues.apache.org/jira/browse/DRILL-2884
Project: Apache Drill
Issue Type: Bug
Reporter: Daniel Barclay (Drill)
After Statement.cancel() is called for a SQL statement's execution, a
subsequent call to a method on the ResultSet for that execution yields a
"ResultSet already closed" exception. (This isn't fully implemented yet, but
it is for, e.g., next().)
A call to cancel() should result in an explicit "execution canceled" exception
rather than the usual "already closed" exception (so that it doesn't seem like
a Drill programming error rather an expected result of canceling).
