------------------------------
Summary: EXIT handler not exiting properly if triggered from
another EXIT handler
Key: SPARK-53758
URL: https://issues.apache.org/jira/browse/SPARK-53758
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 4.0.1, 4.1.0
Reporter: Teodor
An unexpected behavior happens when an EXIT handler inside of an outer scope
gets triggered by an exception inside an EXIT handler thats inside an inner
nested scope: instead of leaving the outer scope after finishing all the
exception handling, execution only leaves the inner scope.
Example:
{code:java}
BEGIN
DECLARE VARIABLE flag INT = -1;
l1: BEGIN
DECLARE EXIT HANDLER FOR UNRESOLVED_COLUMN.WITHOUT_SUGGESTION
BEGIN
SELECT flag;
SET flag = 2;
END;
l2: BEGIN
DECLARE EXIT HANDLER FOR DIVIDE_BY_ZERO
BEGIN
SELECT flag;
SET flag = 1;
select X; -- select non existing variable
SELECT 2;
END;
SELECT 5;
SELECT 1/0; -- divide by zero
SELECT 6;
END l2;
SELECT 3, flag;
END l1;
END {code}
