public Decision canAllocate(ShardRouting shardRouting, RoutingAllocation allocation)
AllocationDecider
Decision
whether the given shard routing can be allocated at all at this state of the
RoutingAllocation
. The default is Decision.ALWAYS
.canAllocate
in class AllocationDecider
public Decision canAllocate(ShardRouting shardRouting, RoutingNode node, RoutingAllocation allocation)
AllocationDecider
Decision
whether the given shard routing can be
allocated on the given node. The default is Decision.ALWAYS
.canAllocate
in class AllocationDecider
public Decision canForceAllocatePrimary(ShardRouting shardRouting, RoutingNode node, RoutingAllocation allocation)
AllocationDecider
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
