> Due to a bug I haven't been able to reproduce the production cluster had
> unknown column names. To replicate the issue for this test I did the
> following:
> {noformat}
> $ ccm create -v 2.1.19 -n 1 -s bug
> $ cat > schema.cql << 'EOF'
> CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy',
> 'replication_factor': '1'} AND durable_writes = true;
> CREATE TABLE test.unknowntest (id int primary key, payload text, "paylo!d"
> text);
> EOF
> $ ccm node1 cqlsh -f schema.cql
> $ export CASSANDRA_INCLUDE=~/.ccm/bug/node1/bin/cassandra.in.sh
> $ cat > bug.json << 'EOF'
> [
> {"key": "1",
> "cells": [["","",1554432501209207],
> ["paylo!d","hello world",1554432501209207],
> ["payload","hello world",1554432501209207]]}
> ]
> EOF
> $ ~/.ccm/repository/2.1.19/tools/bin/json2sstable -K test -c unknowntest
> ~/bug.json
> ~/.ccm/bug/node1/data0/test/unknowntest-<cfid>/test-unknowntest-ka-1-Data.db{noformat}
> Then test the behavior of unknown columns in 2.1:
> {noformat}
> $ ccm stop
> $ ccm create -v 2.1.19 -n 1 -s bug2_1_19
> $ cat > schema2.cql << 'EOF'
> CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy',
> 'replication_factor': '1'} AND durable_writes = true;
> CREATE TABLE test.unknowntest (id int primary key, payload text);
> EOF
> $ ccm node1 cqlsh -f schema2.cql
> $ ccm stop
> $ cp ~/.ccm/bug/node1/data0/test/unknowntest-<cfid>/test-unknowntest-ka-1-*
> ~/.ccm/bug2_1_19/node1/data0/test/unknowntest-<cfid>/
> $ ccm start
> $ ccm node1 cqlsh
> Connected to bug2_1_19 at 127.0.0.1:9042.
> [cqlsh 5.0.1 | Cassandra 2.1.19 | CQL spec 3.2.1 | Native protocol v3]
> Use HELP for help.
> cqlsh> select * from test.unknowntest where id = 1;
> id | payload
> ----+-------------
> 1 | hello world
> (1 rows){noformat}
> Compared to 3.11.4 which did the following:
> {noformat}
> $ ccm stop
> $ ccm create -v 3.11.4 -n 1 -s bug3_11_4
> $ ccm node1 cqlsh -f schema2.cql
> $ ccm stop
> $ cp ~/.ccm/bug/node1/data0/test/unknowntest-<cfid>/test-unknowntest-ka-1-*
> ~/.ccm/bug3_11_4/node1/data0/test/unknowntest-<cfid>/
> $ ccm start
> $ ccm node1 cqlsh
> Connected to bug3_11_4 at 127.0.0.1:9042.
> [cqlsh 5.0.1 | Cassandra 3.11.4 | CQL spec 3.4.4 | Native protocol v4]
> Use HELP for help.
> cqlsh> select * from test.unknowntest where id = 1;
> ReadFailure: Error from server: code=1300 [Replica(s) failed to execute read]
> message="Operation failed - received 0 responses and 1 failures"
> info={'failures': 1, 'received_responses': 0, 'required_responses': 1,
> 'consistency': 'ONE'}
> {noformat}
> In the logs this resulted in an IllegalStateException from LegacyLayout line
> 1127
> The expected behavior would be to ignore the column and return results the
> same as in 2.1
