-----------------------------------------

             Summary: QueryProcessor.executeInternal(statement) are never 
evicted from internal cache
                 Key: CASSANDRA-8693
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8693
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Edward Ribeiro
             Fix For: 2.1.2
         Attachments: qp-internal.patch

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.
