Example 1 with HostStateChangeDeniedException

use of com.yahoo.vespa.orchestrator.policy.HostStateChangeDeniedException in project vespa by vespa-engine.

the class StorageNodeImpl method setNodeState.

@Override

    // The "cluster name" used by the Cluster Controller IS the cluster ID.
    String clusterId = this.clusterId.s();

    ClusterControllerClient client = clusterControllerClientFactory.createClient(clusterControllers, clusterId);

Example 2 with HostStateChangeDeniedException

use of com.yahoo.vespa.orchestrator.policy.HostStateChangeDeniedException in project vespa by vespa-engine.

the class OrchestratorImplTest method whenSuspendAllFails.

@Test
