@Deprecated
public class DisableAllocationDecider
extends AllocationDecider

This AllocationDecider prevents cluster-wide shard allocations. The behavior of this AllocationDecider can be changed in real-time via the cluster settings API. It respects the following settings:

• cluster.routing.allocation.disable_new_allocation - if set to true no new shard-allocation are allowed. Note: this setting is only applied if the allocated shard is a primary and it has not been allocated before the this setting was applied.
• cluster.routing.allocation.disable_allocation - if set to true cluster wide allocations are disabled
• cluster.routing.allocation.disable_replica_allocation - if set to true cluster wide replica allocations are disabled while primary shards can still be allocated

Note: all of the above settings might be ignored if the allocation happens on a shard that explicitly ignores disabled allocations via RoutingAllocation.ignoreDisable(). Which is set if allocation are explicit.
