---------------------------------------
Summary: Better handling of missing entries in
system_schema.columns during startup
Key: CASSANDRA-13180
URL: https://issues.apache.org/jira/browse/CASSANDRA-13180
Project: Cassandra
Issue Type: Improvement
Components: Distributed Metadata
Reporter: Tyler Hobbs
Assignee: Tyler Hobbs
Fix For: 3.0.x, 3.x
Like the error in CASSANDRA-12213 and CASSANDRA-12165, it's possible for
{{system_schema.keyspaces}} and {{tables}} to contain entries for a table while
{{system_schema.columns}} has none. This produces an error during startup, and
there's no way for a user to recover from this without restoring from backups.
Although this has been seen in the wild on one occasion, the cause is still not
entirely known. (It may be due to a concurrent DROP TABLE and ALTER TABLE
where a table property is altered.) Until we know the root cause, it makes
sense to give users a way to recover from that situation.
