Method Detail

canAllocate

public Decision canAllocate(ShardRouting shardRouting,
                            RoutingNode node,
                            RoutingAllocation allocation)

Description copied from class: AllocationDecider

Returns a Decision whether the given shard routing can be allocated on the given node. The default is Decision.ALWAYS.

Overrides:

canAllocate in class AllocationDecider

canAllocate

public Decision canAllocate(ShardRouting shardRouting,
                            RoutingAllocation allocation)

Description copied from class: AllocationDecider

Returns a Decision whether the given shard routing can be allocated at all at this state of the RoutingAllocation. The default is Decision.ALWAYS.

Overrides:

canAllocate in class AllocationDecider

canForceAllocatePrimary

public Decision canForceAllocatePrimary(ShardRouting shardRouting,
                                        RoutingNode node,
                                        RoutingAllocation allocation)

Description copied from class: AllocationDecider

Returns a Decision whether the given primary shard can be forcibly allocated on the given node. This method should only be called for unassigned primary shards where the node has a shard copy on disk. Note: all implementations that override this behavior should take into account the results of AllocationDecider.canAllocate(ShardRouting, RoutingNode, RoutingAllocation) before making a decision on force allocation, because force allocation should only be considered if all deciders return Decision.NO.

Overrides:

canForceAllocatePrimary in class AllocationDecider
