Description

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.
