The new_test_keyspace context manager in test/cluster/util.py uses DROP KEYSPACE without IF EXISTS during cleanup. The Python driver has a known bug (scylladb/python-driver#317) where connection pool renewal after concurrent node bootstraps causes double statement execution. The DROP succeeds server-side, but the response is lost when the old pool is closed. The driver retries on the new pool, and gets ConfigurationException message "Cannot drop non existing keyspace". The CREATE KEYSPACE in create_new_test_keyspace already uses IF NOT EXISTS as a workaround for the same driver bug. This patch applies the same approach to fix DROP KEYSPACE. Fixes SCYLLADB-1538 Closes scylladb/scylladb#29487

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
