Using a describe columnfamilies/tables query, Cassandra only gives me <empty> in 1.2.0-beta1 and the error mentioned in https://issues.apache.org/jira/browse/CASSANDRA-4946 in 1.2.0-beta2, despite there actually being columnfamilies in the currently selected/used keyspace. Selecting/updating the columnfamilies and describe columnfamily statements work fine.
Is this a bug that will eventually be fixed, or does describe columnfamilies only list the columnfamilies after certain conditions (e.g. only after they've been flushed to the disk) have been met? If so, what are these conditions, and is there any way to force Cassandra to execute the necessary steps to meet these conditions?
