Dmitry Konstantinov commented on CASSANDRA-19165:
-------------------------------------------------
ok, I think the root cause is the following. As a part of the test setup we
create users used later in the tests:
{code:java}
executeAs(Arrays.asList("CREATE ROLE testuser WITH LOGIN = true AND SUPERUSER =
false AND PASSWORD = 'foo'",
"CREATE ROLE testuser_nologin WITH LOGIN = false AND
SUPERUSER = false AND PASSWORD = 'foo'",
"CREATE KEYSPACE testks WITH replication = {'class':
'SimpleStrategy', 'replication_factor': '1'}",
"CREATE TABLE testks.table1 (a text, b int, c int,
PRIMARY KEY (a, b))",
"CREATE TABLE testks.table2 (a text, b int, c int,
PRIMARY KEY (a, b))"),
"cassandra", "cassandra", null); {code}
We use default cassandra user to do it and executeAs actually ignores
AuthenticationException in this case, so we do not notice it.
It actually happen based on a log for a failed test run from CI (
[^TEST-org.apache.cassandra.transport.CQLUserAuditTest.log] ):
{code}
DEBUG [cluster1-nio-worker-0] 2026-01-28T07:41:10,135 Defuncting
Connection[localhost/127.0.0.1:9042-1, inFlight=0, closed=false] because:
Authentication error on host localhost/127.0.0.1:9042: Provided username
cassandra and/or password are incorrect
{code}
Why do we have this error after Cassandra startup? Because default cassandra
role creation is executed in async way, in a separate thread pool:
* org.apache.cassandra.service.StorageService#doAuthSetup(boolean)
* org.apache.cassandra.auth.CassandraRoleManager#scheduleSetupTask
Even if we set SUPERUSER_SETUP_DELAY_MS.setLong(0) still there is a probability
to have the job executed after our user creation logic.
We can observe it in the log:
{code}
DEBUG [cluster1-nio-worker-0] 2026-01-28T07:41:10,135 Defuncting
Connection[localhost/127.0.0.1:9042-1, inFlight=0, closed=false] because:
Authentication error on host localhost/127.0.0.1:9042: Provided username
cassandra and/or password are incorrect
{code}
executed before cassandra role creation:
{code}
INFO [OptionalTasks:1] 2026-01-28T07:41:10,355 Created default superuser role
'cassandra'
{code}
So, to make the test reliable we need to wait for cassandra role creation in
the test setup before other roles creation.
