> Compacting a CF with a secondary index throws an assertion error while 
> opening readers for the secondary index components. It is trying to update 
> the CFMD to null because it could not find a CFMD which describes the 
> secondary index. The CompressionParameters are shared between the data and 
> the secondary indices.
> Was introduced in CASSANDRA-7978.
