Description

This test starts a cluster, then starts the ZKFCs, then tries to issue a manual failover. But, it doesn't wait until the ZKFCs are fully done starting up. So, I see a test run occasionally fail because the failover says that the NN is not ready yet. The test just needs to wait until the ZKFCs are in "healthy" state before proceeding.
