> Tes MultiNodeTest#testQuorumOverride is racey. The test verifies the behaviour of a group when all the replicas are killed and quorum override is applied to allow the master to continue in isolation.
> The test currently assumes that failover doesn't occur. This is wrong, failover may occur if the master discovers itself alone before the quorum override is applied. This discovery is asynchronous. The test cannot predict if failover will occur of not.
> In the unlucky case where failure occurs, the the failover happens whilst the test is committing a transaction. The transaction will correctly. The test does include code to retry failed transactions.
