--------------------------------------
Attachment: 3288.txt
patch to explicitly ignore client-set ids on create
> CfDef can default to an invalid id and fail during system_add_column_family

> Key: CASSANDRA-3288
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3288
> Project: Cassandra

> The line from this commit:
> https://github.com/apache/cassandra/commit/38e3e85b121ba6308ba3ceb26312d12ed0d609ec#L1R683
> Introduced an issue in that some clients, particularly Hector, will send a
> CfDef with an ID having been set to 0. Done via the CfDef#setId, the isSetId
> bit is flipped to true, causing error if schemaId of 0 already exists, which
> given the use case, is likely.
> Since we know the context of a system_create_column_family, this can be
> sidestepped by just stepping on whatever ID is there (irrelevant on a create
> anyway) with the value returned from: Schema.instance.nextCFId()
