Sylvain Lebresne updated CASSANDRA-11064:
-----------------------------------------
Reproduced In: 3.2.1, 3.2 (was: 3.2, 3.2.1)
Reviewer: Sylvain Lebresne
> Failed aggregate creation breaks server permanently
> ---------------------------------------------------
>
> Key: CASSANDRA-11064
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11064
> Project: Cassandra
> Issue Type: Bug
> Reporter: Olivier Michallat
> Assignee: Robert Stupp
> Fix For: 3.0.x
>
>
> While testing edge cases around aggregates, I tried the following to see if custom types were supported:
> {code}
> ccm create v321 -v3.2.1 -n3
> ccm updateconf enable_user_defined_functions:true
> ccm start
> ccm node1 cqlsh
> CREATE FUNCTION id(i 'DynamicCompositeType(s => UTF8Type, i => Int32Type)')
> RETURNS NULL ON NULL INPUT
> RETURNS 'DynamicCompositeType(s => UTF8Type, i => Int32Type)'
> LANGUAGE java
> AS 'return i;';
> // function created successfully
> CREATE AGGREGATE ag()
> SFUNC id
> STYPE 'DynamicCompositeType(s => UTF8Type, i => Int32Type)'
> INITCOND 's@foo:i@32';
> ServerError: <ErrorMessage code=0000 [Server error] message="java.lang.RuntimeException: java.util.concurrent.ExecutionException: org.apache.cassandra.exceptions.SyntaxException: Failed parsing CQL term: [s@foo:i@32] reason: SyntaxException line 1:1 no viable alternative at character '@'">{code}
> Despite the error, the aggregate appears in system tables:
> {code}
> select * from system_schema.aggregates;
> keyspace_name | aggregate_name | ...
> ---------------+----------------+ ...
> test | ag | ...
> {code}
> But you can't drop it, and trying to drop its function produces the server error again:
> {code}
> DROP AGGREGATE ag;
> InvalidRequest: code=2200 [Invalid query] message="Cannot drop non existing aggregate 'test.ag'"
> DROP FUNCTION id;
> ServerError: <ErrorMessage code=0000 [Server error] message="java.lang.RuntimeException: java.util.concurrent.ExecutionException: org.apache.cassandra.exceptions.SyntaxException: Failed parsing CQL term: [s@foo:i@32] reason: SyntaxException line 1:1 no viable alternative at character '@'">
> {code}
> What's worse, it's now impossible to restart the server:
> {code}
> ccm stop; ccm start
> org.apache.cassandra.exceptions.SyntaxException: Failed parsing CQL term: [s@foo:i@32] reason: SyntaxException line 1:1 no viable alternative at character '@'
