Jeff Jirsa commented on CASSANDRA-13559:
----------------------------------------

If this is really just a single version change, this is a tiny nonissue that doesn't justify pulling the package - CASSANDRA-13441 is present in .13 and earlier 3.0 versions will cause far more schema changes than this patch will for anyone upgrading from 2.1/2.2. This is worth fixing, but I don't see why it's worth pulling binaries.

> As the order of SchemaKeyspace is changed ([6991556 | https://github.com/apache/cassandra/commit/6991556e431a51575744248a4c484270c4f918c9], CASSANDRA-12213), the result of function [{{calculateSchemaDigest}}|https://github.com/apache/cassandra/blob/cassandra-3.0/src/java/org/apache/cassandra/schema/SchemaKeyspace.java#L311] is also changed for the same schema. Which causes schema mismatch while upgrading 3.0.x -> 3.0.13.
