When ScalarExprEvaluator::Clone() fails, the newly created evaluator was not added to the output vector. This makes it impossible for callers to close and clean up the evaluators afterwards. This change fixes this by always adding the newly created evaluator to the output vector before checking for the error status. This path is only exercised in the scanner code. Two new tests are added to exercise the failure paths. Testing done: newly added tests in udf-errors.test Change-Id: I45ffd722d0a69ad05ae3c748cf504c7f1a959a1d Reviewed-on: http://gerrit.cloudera.org:8080/8572 Reviewed-by: Tim Armstrong <tarmstrong@cloudera.com> Tested-by: Impala Public Jenkins
