Method Detail

applyStartedShards

public RoutingAllocation.Result applyStartedShards(ClusterState clusterState,
                                                   List<? extends ShardRouting> startedShards)

Applies the started shards. Note, shards can be called several times within this method.

If the same instance of the routing table is returned, then no change has been made.

applyFailedShard

public RoutingAllocation.Result applyFailedShard(ClusterState clusterState,
                                                 ShardRouting failedShard)

Applies the failed shards. Note, shards can be called several times within this method.

If the same instance of the routing table is returned, then no change has been made.

reroute

public RoutingAllocation.Result reroute(ClusterState clusterState)

Reroutes the routing table based on the live nodes.

If the same instance of the routing table is returned, then no change has been made.

rerouteWithNoReassign

public RoutingAllocation.Result rerouteWithNoReassign(ClusterState clusterState)

Only handles reroute but *without* any reassignment of unassigned shards or rebalancing. Does make sure to handle removed nodes, but only moved the shards to UNASSIGNED, does not reassign them.
