["Carl Yeksigian (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-8027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14156656#comment-14156656 ] 

Carl Yeksigian commented on CASSANDRA-8027:
-------------------------------------------

We can just use the metadata that we already have if it is not a secondary index instead of looking it up in the schema. Otherwise, LGTM.

> 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.
