> In test_otel_trace.py, the test_ddl_createtable_fail has a potential to be flaky.  In the test, the second coordinator that drops the database may run that DDL too quickly before the create database operation executed on the first coordinator propagates to the second coordinator.
> In the test, first retrieve the number of databases from the "catalog.num-databases" metric:
> {code:python}
> num_dbs = self.cluster.get_first_impalad().service.get_metric_value("catalog.num-databases")
> {code}
> Then, before the drop database DDL, wait for the second coordinator's "catalog.num-databases" metric to increment by 1:
> {code:python}
> self.cluster.impalads[1].service.wait_for_metric_value("catalog.num-databases", num_dbs + 1, 60)
> {code}
