There was a problem hiding this comment.
Because this test has only 2 pd's and five ResignLeader times, whenever there is a network or disk problem(ci machine has a high probability) will cause the lease to expire, and result in one more leader resigning.
And then there is a high probability of being recognized as frequent campaign times to transfer leader failed
