Jay Zhuang created CASSANDRA-14379:
--------------------------------------
Summary: Better handling of missing partition columns in
system_schema.columns during startup
Key: CASSANDRA-14379
URL: https://issues.apache.org/jira/browse/CASSANDRA-14379
Project: Cassandra
Issue Type: Improvement
Components: Distributed Metadata
Reporter: Jay Zhuang
Assignee: Jay Zhuang
Follow up for CASSANDRA-13180, during table deletion/creation, we saw one table
having partially deleted columns (no partition column, only regular column).
It's blocking node from startup:

java.lang.AssertionError: null

As partition column is mandatory, it should throw
[{{MissingColumns}}|https://github.com/apache/cassandra/blob/60563f4e8910fb59af141fd24f1fc1f98f34f705/src/java/org/apache/cassandra/schema/SchemaKeyspace.java#L1351],
the same as CASSANDRA-13180, so the user is able to cleanup the schema.
