Example 57 with Node

use of com.yahoo.vdslib.state.Node in project vespa by vespa-engine.

the class ClusterStateGeneratorTest method unstable_retired_node_should_be_marked_down.

/**
 * The generated state must be considered over the Reported state when deciding whether
 * to override it with the Wanted state. Otherwise, an unstable retired node could have
 * its generated state be Retired instead of Down. We want it to stay down instead of
 * potentially contributing additional instability to the cluster.
