Benjamin Lerer commented on CASSANDRA-15269:
--------------------------------------------
[~bereng] Sorry, for the delay. There are a simple way to trigger the
{{ClassCastException}} without changing anything to the code.
I pushed a new version of the patch
[here|https://github.com/apache/cassandra/commit/473e67199eb29f831000782ab25cdf56629af1c8].

> Cassandra fails to process OperationExecutionException which causes
> ClassCastException
> --------------------------------------------------------------------------------------
>
> Key: CASSANDRA-15269
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15269
> Project: Cassandra
> Issue Type: Bug
> Components: CQL/Interpreter
> Reporter: Liudmila Kornilova
> Assignee: Berenguer Blasi
> Priority: Normal
> Fix For: 4.0.x
>
>
> While working on CASSANDRA-15232 I noticed that OperationExecutionException
> is not processed correctly.
> How to reproduce the issue:
> 1. {{create table d (numerator decimal primary key, denominator decimal);}}
> 2. {{insert into d (numerator, denominator) values
> (123456789112345678921234567893123456, 2);}}
> 3. {{select numerator % denominator from d;}}
> What happens:
> 1. remainder operation throws ArithmeticException (BigDecimal:1854)
> 2. The exception is wrapped in OperationExecutionException
> 3. ClassCastException appears (OperationExecutionException cannot be cast to
> FunctionExecutionException at ErrorMessage.java:280)
> What should happen:
> OperationExecutionException with message "the operation 'decimal % decimal'
> failed: Division impossible" should be delivered to user
> Note that after fixing CASSANDRA-15232 {{select numerator % denominator from
> d;}} will produce correct result of remainder operation.
> Currently I am not aware of other cases when OperationExecutionException may
> be treated as FunctionExecutionException
