[jira] [Created] (CASSANDRA-12516) Interned column identifiers can be overridden incorrectly

Aleksey Yeschenko created CASSANDRA-12516:
---------------------------------------------

             Summary: Interned column identifiers can be overridden incorrectly
                 Key: CASSANDRA-12516
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12516
             Project: Cassandra
          Issue Type: Bug
            Reporter: Aleksey Yeschenko
            Assignee: Stefania
             Fix For: 2.1.x, 2.2.x, 3.0.x, 3.x


As discovered by [~Stefania] in CASSANDRA-12423, our use of {{ColumnIdentifier.internedInstances}} to map byte buffer column names to column identifiers is incorrect. It's possible for two non-equal {{ColumnIdentifier}} instances to have the same {{ByteBuffer}} as raw name, and yet different text representations, due to different column name types, leading to hard to debug correctness issues.

Should either amend the map to have the type as part of the key, or limit the use of that map.
