Chris Lohfink commented on CASSANDRA-14199:
-------------------------------------------
duplicate of CASSANDRA-12594 and CASSANDRA-13573 ? looks like it should be
fixed in 3.0.x now, which version specifically are you using?

> *Steps to reproduce:*
> {code:java}
> cqlsh> create TABLE stresscql.sstabledump_test(userid text PRIMARY KEY, c1
> list<uuid>, c2 frozen<list<uuid>>, c3 set<text>, c4 frozen<set<text>>, c5
> map<text,text>, c6 frozen<map<text,text>>);
> cqlsh> insert INTO stresscql.sstabledump_test (userid, c1, c2, c3, c4, c5,
> c6) VALUES ( 'id', [6947e8c0-02fa-11e8-87e1-fb0d0e20b5c4],
> [6947e8c0-02fa-11e8-87e1-fb0d0e20b5c4], {'set', 'user'}, {'view', 'over'},
> {'good': 'hello', 'root': 'text'}, {'driver': 'java', 'note': 'new'});{code}
>
> *Root cause:*
> Frozen collection is treated as simple column and it's the client's
> responsibility to parse the data from ByteBuffer. We have this logic in
> different drivers but sstabledump doesn't have the logic in place. It just
> treat the whole collection as a single UUID.
