--------------------------------------
Environment: Successfully reproducible on a single-node Mac OS X Yosemite
10.10.5 cluster and a 6-node 2-DC CentOS 6.9 cluster. (was: Successfully
reproducible on a single-node Mac OS X Yosemite 10.10.5 cluster and a 6-node

> UDAs that instantiate UDTs break after restart
> ----------------------------------------------
>
> Key: CASSANDRA-13966
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13966
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Successfully reproducible on a single-node Mac OS X
> Yosemite 10.10.5 cluster and a 6-node 2-DC CentOS 6.9 cluster.
> Reporter: Benjamin Shen
> Fix For: 3.11.x

> When testing performance optimizations for for UDAs, I noticed that, when
> instantiated using udfContext, newly created UDTs would cause a UDA to break,
> but ONLY after restart. This is pretty concern for us to deploy UDAs in a
> production setting, as it feels like a consistency error.
> When run without restarting Cassandra, this CQL script produces no errors and
> the expected result:
> {code}-- Create and USE your own keyspace
> CREATE TYPE testing_type (
> a int
> );
> CREATE OR REPLACE FUNCTION
> testing_state (
> state int
> )
> CALLED ON NULL INPUT RETURNS
> int
> LANGUAGE java AS
> '
> return state+1;
> ';
> CREATE OR REPLACE FUNCTION
> testing_final(state int)
> CALLED ON NULL INPUT RETURNS int LANGUAGE java AS
> '
> udfContext.newUDTValue("testing_type");
> return state;';
> CREATE OR REPLACE AGGREGATE testing_uda()
> SFUNC testing_state
> STYPE int
> FINALFUNC testing_final
> INITCOND 0;
> CREATE TABLE IF NOT EXISTS testing_table (
> "a" int,
> PRIMARY KEY ("a")
> ) WITH gc_grace_seconds=0
> AND COMPACTION={'class': 'TimeWindowCompactionStrategy',
> 'compaction_window_unit': 'DAYS', 'compaction_window_size': '1'};
> SELECT testing_uda() FROM testing_table;{code}
> However, if you then restart Cassandra on the local node and rerun the last
> line again:
> {code}
> -- Restart Cassandra after running previous script
> cqlsh:my_keyspace> SELECT testing_uda() FROM testing_table;
> Traceback (most recent call last):
