Example 53 with NodeState

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

the class ClusterStateGeneratorTest method implicit_down_while_listing_buckets_does_not_override_wanted_state.

/**
 * Implicit down while reported as init should not kick into effect if the Wanted state

Example 54 with NodeState

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

the class ClusterStateGeneratorTest method storage_node_in_init_mode_while_listing_buckets_is_marked_down.

/**
 * A storage node will report itself as being in initializing mode immediately when
 * starting up. It can only accept external operations once it has finished listing
 * the set of buckets (but not necessarily their contents). As a consequence of this,
 * we have to map reported init state while bucket listing mode to Down. This will
 * prevent clients from thinking they can use the node and prevent distributors form
 * trying to fetch yet non-existent bucket sets from it.
 *
 * Detecting the bucket-listing stage is currently done by inspecting its init progress
 * value and triggering on a sufficiently low value.

Example 55 with NodeState

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

the class ClusterStateGeneratorTest method distribution_bit_not_influenced_by_nodes_down_or_in_maintenance.

// TODO do we really want this behavior? It's the legacy one, but it seems... dangerous.. Especially for maintenance
// TODO We generally want to avoid distribution bit decreases if at all possible, since "collapsing"
// the top-level bucket space can cause data loss on timestamp collisions across super buckets.
