[jira] Reopened: (CASSANDRA-891) Add ValidateWith to CF definitions

["Stu Hood (JIRA)" <ji...@apache.org>]

Stu Hood reopened CASSANDRA-891:
--------------------------------


Needs a default value for default_validation_class in order to handle users upgrading from beta1 to beta2. See CASSANDRA-1437 for a full explanation of the issue, but in summary, something like:
{{union { null, string } default_validation_class = null;}}
...should mean the CfMetaData.inflate will see a null on default_validation_class, rather than the schema failure caused by r989344.

> VW would take an AbstractType like CompareWith and validate the data on insert.  Should default to BytesType (i.e. no-op).
> This would have the side effect of giving the CLI enough information about values to parse and display them intelligently rather than just hex byte values.
