Stefan Miklosovic created CASSANDRA-20237:
---------------------------------------------
Summary: Error on server side when trying to provide a TupleType
to select on where target type is UTF8Type
Key: CASSANDRA-20237
URL: https://issues.apache.org/jira/browse/CASSANDRA-20237
Project: Apache Cassandra
Issue Type: Bug
Reporter: Stefan Miklosovic
I just found this by accident.
{noformat}
cassandra@cqlsh> select * from system_views.settings where name =
('authorizer.class_name', 'role_manager_class_name');
NoHostAvailable: ('Unable to complete the operation against any hosts', {<Host:
127.0.0.1:9042 datacenter1>: <Error from server: code=0000 [Server error]
message="java.lang.ClassCastException: class

'app')">})
{noformat}
Then on server side:

This does not seem to be a problem for other types like sets, maps or lists:
{noformat}
cassandra@cqlsh> select * from system_views.settings where name =
{'authorizer.class_name', 'role_manager_class_name'};
InvalidRequest: Error from server: code=2200 [Invalid query] message="Invalid
set literal for name of type text"
cassandra@cqlsh> select * from system_views.settings where name =
['authorizer.class_name', 'role_manager_class_name'];
InvalidRequest: Error from server: code=2200 [Invalid query]
message="Unexpected receiver type 'text'; only list and vector are expected"
cassandra@cqlsh> select * from system_views.settings where name =
{'authorizer.class_name': 'a', 'role_manager_class_name': 'b'};
InvalidRequest: Error from server: code=2200 [Invalid query] message="Invalid
map literal for name of type text"
{noformat}
I would expect that tuples would be treated the same way.
