---------------------------------------------
Summary: Node start can fail if the base table of a materialized
view is not found
Key: CASSANDRA-13737
URL: https://issues.apache.org/jira/browse/CASSANDRA-13737
Project: Cassandra
Issue Type: Bug
Components: Distributed Metadata, Materialized Views
Reporter: Andrés de la Peña
Assignee: Andrés de la Peña
Fix For: 3.0.x, 3.11.x, 4.x
Node start can fail if the base table of a materialized view is not found,
which is something that can happen under certain circumstances. There is a
dtest reproducing the problem:
{code}
cluster = self.cluster
cluster.populate(3)
cluster.start()
node1, node2, node3 = self.cluster.nodelist()
session = self.patient_cql_connection(node1,
consistency_level=ConsistencyLevel.QUORUM)
create_ks(session, 'ks', 3)
session.execute('CREATE TABLE users (username varchar PRIMARY KEY, state
varchar)')
node3.stop(wait_other_notice=True)
# create a materialized view only in nodes 1 and 2
session.execute(('CREATE MATERIALIZED VIEW users_by_state AS '
'SELECT * FROM users WHERE state IS NOT NULL AND username IS
NOT NULL '
'PRIMARY KEY (state, username)'))
node1.stop(wait_other_notice=True)
node2.stop(wait_other_notice=True)
# drop the base table only in node 3
node3.start(wait_for_binary_proto=True)
session = self.patient_cql_connection(node3,
consistency_level=ConsistencyLevel.QUORUM)
session.execute('DROP TABLE ks.users')
cluster.stop()
cluster.start() # Fails
{code}
This is the error during node start:
{code}
