All Implemented Interfaces:

AllocationCommand, NamedWriteable, Writeable, ToXContent, ToXContentObject

public class AllocateEmptyPrimaryAllocationCommand
extends BasePrimaryAllocationCommand

Allocates an unassigned empty primary shard to a specific node. Use with extreme care as this will result in data loss. Allocation deciders are ignored.
