> 2.1 sstableloader will fail if there are collections in the schema tables

> Key: CASSANDRA-10700
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10700
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Reporter: Tyler Hobbs
> Assignee: T Jake Luciani
> Fix For: 2.1.x
>
>
> In {{BulkLoader.ExternalClient}}, we use the Thrift {{execute_cql3_query()}}
> method to read the system schema tables. Because it's a Thrift connection,
> we use the v2 protocol format for serializing data. However, when we later
> read the results with {{CFMetadata.fromThriftCqlRow()}}, we use the v3
> protocol format to deserialize the results. If there are any collections in
> the results, such as entries in {{dropped_columns}}, the following error will
> occur:
> {noformat}

> I believe this only affects 2.1 due to the re-working of
> BulkLoader/sstableloader in 2.2 and 3.0, but I haven't confirmed that.
