---------------------------------------------
Summary: SecondaryIndexManagerTest.assert[Not]MarkedAsBuilt
produces flaky tests
Key: CASSANDRA-13965
URL: https://issues.apache.org/jira/browse/CASSANDRA-13965
Project: Cassandra
Issue Type: Bug
Components: Secondary Indexes, Testing
Reporter: Andrés de la Peña
Assignee: Andrés de la Peña
Priority: Minor
Fix For: 4.x
The methods
[{{SecondaryIndexManagerTest.assertMarkedAsBuilt}}|https://github.com/apache/cassandra/blob/trunk/test/unit/org/apache/cassandra/index/SecondaryIndexManagerTest.java#L554-L557]
and
[{{SecondaryIndexManagerTest.assertNotMarkedAsBuilt}}|https://github.com/apache/cassandra/blob/trunk/test/unit/org/apache/cassandra/index/SecondaryIndexManagerTest.java#L559-L562]
produce occasional test failures.
These methods assume that there aren't any other indexes in the
{{system.IndexInfo}} table than those created by the calling test. However, it
is possible to find indexes built for other tests (not only
{{SecondaryIndexManagerTest}}) that rely on {{CQLTester.afterTest}} to cleanup
to drop their created indexes, because this method is asynchronous. So, it is
possible to reach the {{SecondaryIndexManagerTest.assert(Not)MarkedAsBuilt}}
calls before the indexes created by the previous test have been cleaned up.
