Sam Tunnicliffe commented on CASSANDRA-10934:
---------------------------------------------
The failing dtest is incorrect, creating a values index on a map column which
already has a keys index is permitted since 3.0. dtest PR
[here|https://github.com/riptano/cassandra-dtest/pull/754]
> upgrade_test map_keys_indexing_test is failing

> {{upgrade_tests.cql_tests.TestCQLNodes3RF3.map_keys_indexing_test}} and
> {{upgrade_tests.cql_tests.TestCQLNodes2RF1.map_keys_indexing_test}} are both
> failing. See
> http://cassci.datastax.com/job/cassandra-3.0_dtest/456/testReport/upgrade_tests.cql_tests/TestCQLNodes3RF3/map_keys_indexing_test/
> for an example.
> The tests create a secondary index on the keys of a map, then perform an
> upgrade, then attempt to create secondary index on the values of that map.
> This is expected to fail, as both indices cannot exist at the same time. If
> the index creation happens before the upgrade, it does fail. After the
> upgrade, however, it works. When I check the cluster schema metadata with the
> python driver, I can only see one index after creating the second, rather
> than both.
> Node logs are attached.
