---------------------------------------
Summary: 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
Priority: Minor
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.
