> QueryProcessor holds a reference to {{internalStatements}}, a map for prepared statements used internally.
> Those commands don't mix with the ones created by the user, but the problem is that if a KS/CF is dropped and then recreated {{internalStatements}} entries will point to invalid PreparedStatements (old cf_id) so any operation on those statements will fail therefore. In fact, as of today, this map is never actually cleaned no matter what.
> This problem is similar to the ones addressed by https://issues.apache.org/jira/browse/CASSANDRA-8652 and https://issues.apache.org/jira/browse/CASSANDRA-7566, so those issues provide any further context. 
> I am attaching a patch to this issue.
