EXIT handler (was: EXIT handler not exiting properly if triggered from another
EXIT handler)
> [M1] 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: Sub-task
> Components: Spark Core
> Affects Versions: 4.1.0, 4.0.1
> Reporter: Teodor
> Priority: Major
>
> 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}
>
> Returns 3, 2 at the end, but it shouldn't reach that part of the code.
