Tyler Hobbs commented on CASSANDRA-11609:
-----------------------------------------
The root of the problem was that in the 2.x schema, implicitly frozen types
(like nested UDTs) were not wrapped in {{FrozenType()}}. Before
CASSANDRA-7423, these were still implicitly frozen, so the 2.x -> 3.x migration
correctly converted them. After 7423 this no longer happens, so they need to
be explicitly converted as part of the schema migration.
Migrations from 2.x -> 3.0.x -> 3.x should be fine without this patch.
I attempted to extend {{LegacySchemaMigratorTest}} to cover this, but
unfortunately it doesn't seem possible to create a table that uses a UDT within
the test framework. So, I think we'll need to continue to rely on the existing
upgrade tests for coverage here.
Patch and pending CI runs:

> This was found in the upgrades user_types_test.
> Can also be repro'd with ccm.
> To repro using ccm:
> Create a 1 node cluster on 2.2.x
> Create this schema:
> {noformat}
> create keyspace test2 with replication = {'class':'SimpleStrategy',
> 'replication_factor':1};
> use test2;
> CREATE TYPE address (
> street text,
> city text,
> zip_code int,
> phones set<text>
> );
> CREATE TYPE fullname (
> irstname text,
> astname text
> );
> CREATE TABLE users (
> d uuid PRIMARY KEY,
> ame frozen<fullname>,
> ddresses map<text, frozen<address>>
> );
> {noformat}
> Upgrade the single node to trunk, attempt to start the node up. Start will
> fail with this exception:
> {noformat}
