forceAnnounceNewColumnFamily

public static void forceAnnounceNewColumnFamily(CFMetaData cfm)
                                         throws ConfigurationException

Announces the table even if the definition is already know locally. This should generally be avoided but is used internally when we want to force the most up to date version of a system table schema (Note that we don't know if the schema we force _is_ the most recent version or not, we just rely on idempotency to basically ignore that announce if it's not. That's why we can't use announceUpdateColumnFamily, it would for instance delete new columns if this is not called with the most up-to-date version) Note that this is only safe for system tables where we know the cfId is fixed and will be the same whatever version of the definition is used.
