---------------------------------------
Resolution: Duplicate
> Dropping non existent table using IF EXISTS throws Exception
> ------------------------------------------------------------
>
> Key: CASSANDRA-6708
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6708
> Project: Cassandra
> Issue Type: Bug
> Components: API
> Environment: Ubuntu 12.0.4 with 8+ GB RAM and 40GB hard disk for data
> directory.
> Reporter: Christoph Werres
> Priority: Minor
>
> When using cqlsh console and dropping a non existent table, an exception is
> thrown although the IF EXISTS condition was given. Also when using the Java
> driver, an InvalidQueryException is thrown in such a situation. This is very
> misleading in applications that suppose such requests to be valid. In earlier
> versions it was a no-op call in that case. This is cqlsh output using
> Cassandra 2.0.5 version:
> {noformat}
> [cqlsh 4.1.1 | Cassandra 2-0-5 | CQL spec 3.1.1 | Thrift protocol 19.39.0]
> Use HELP for help.
> cqlsh> USE mwerrch;
> cqlsh:mwerrch> DESC TABLES;
> cql3test
> cqlsh:mwerrch> DROP TABLE IF EXISTS noexist;
> Bad Request: unconfigured columnfamily noexist
> cqlsh:mwerrch>
> {noformat}
