Description: {{TestZKFailoverController#testGracefulFailoverMultipleZKfcs}}

{{GenericTestUtils.waitFor()}} to retry the assertions. (was: h6. Error Message

Unable to become active. Local node did not get an opportunity to do so from
ZooKeeper, or the local node took too long to transition to active.
