If an active Resource Manager in a cluster fails, to ensure that another Resource Manager is available, the Resource Manager high availability (HA) should be enabled and configured.
In HDP 2.2 or later environment, high availability (HA) can be configured for ResourceManager by using the Enable ResourceManager HA wizard. To ensure this, there must be at least three hosts in the cluster and Apache ZooKeeper servers should be running.
