Example 16 with Node

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

the class NodeInfoTest method down_wanted_state_overrides_config_retired_state.

@Test
public void down_wanted_state_overrides_config_retired_state() {
    ClusterFixture fixture = ClusterFixture.forFlatCluster(3).markNodeAsConfigRetired(1).proposeStorageNodeWantedState(1, State.DOWN);
    NodeInfo nodeInfo = fixture.cluster.getNodeInfo(new Node(NodeType.STORAGE, 1));
    assertEquals(State.DOWN, nodeInfo.getWantedState().getState());
}

Example 17 with Node

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

the class NodeInfoTest method zeroing_crash_count_resets_unstable_init_flag.

/**
 * The cluster controller will, after a time of observed stable state, reset the crash
 * counter for a given node. This should also reset the unstable init flag to keep it
 * from haunting a now stable node.
 */
@Test
public void zeroing_crash_count_resets_unstable_init_flag() {
    ClusterFixture fixture = fixtureWithNodeMarkedAsUnstableInit(1);
    final NodeInfo nodeInfo = fixture.cluster.getNodeInfo(new Node(NodeType.STORAGE, 1));
    nodeInfo.setPrematureCrashCount(0);
    assertFalse(nodeInfo.recentlyObservedUnstableDuringInit());
}

Example 18 with Node

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

the class NodeInfoTest method non_zero_crash_count_update_does_not_reset_unstable_init_flag.

/**
 * A non-zero crash count update, on the other hand, implies the node is suffering
 * further instabilities and should not clear the unstable init flag.
 */
@Test

}

Example 19 with Node

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