所有已实现的接口:

DeclarativeSlotPool

public class BlocklistDeclarativeSlotPool
extends DefaultDeclarativeSlotPool

A DeclarativeSlotPool implementation that supports blocklist. This implementation will avoid allocating slots that located on blocked nodes. The core idea is to keep the slot pool in such a state: there is no slot in slot pool that is free (no task assigned) and located on blocked nodes.

方法详细资料

offerSlots

public Collection<SlotOffer> offerSlots(Collection<? extends SlotOffer> offers,
                                        TaskManagerLocation taskManagerLocation,
                                        TaskManagerGateway taskManagerGateway,
                                        long currentTime)

从接口复制的说明: DeclarativeSlotPool

Offers slots to this slot pool. The slot pool is free to accept as many slots as it needs.

指定者:

offerSlots 在接口中 DeclarativeSlotPool

覆盖:

offerSlots 在类中 DefaultDeclarativeSlotPool

参数:

offers - offers containing the list of slots offered to this slot pool

taskManagerLocation - taskManagerLocation is the location of the offering TaskExecutor

taskManagerGateway - taskManagerGateway is the gateway to talk to the offering TaskExecutor

currentTime - currentTime is the time the slots are being offered

返回:

collection of accepted slots; the other slot offers are implicitly rejected

registerSlots

public Collection<SlotOffer> registerSlots(Collection<? extends SlotOffer> slots,
                                           TaskManagerLocation taskManagerLocation,
                                           TaskManagerGateway taskManagerGateway,
                                           long currentTime)

从接口复制的说明: DeclarativeSlotPool

Registers the given set of slots at the slot pool. The slot pool will try to accept all slots unless the slot is unavailable (for example, the TaskManger is blocked).

The difference from DeclarativeSlotPool.offerSlots(java.util.Collection<? extends org.apache.flink.runtime.taskexecutor.slot.SlotOffer>, org.apache.flink.runtime.taskmanager.TaskManagerLocation, org.apache.flink.runtime.jobmanager.slots.TaskManagerGateway, long) is that this method allows accepting slots which exceed the currently required, but the DeclarativeSlotPool.offerSlots(java.util.Collection<? extends org.apache.flink.runtime.taskexecutor.slot.SlotOffer>, org.apache.flink.runtime.taskmanager.TaskManagerLocation, org.apache.flink.runtime.jobmanager.slots.TaskManagerGateway, long) only accepts those slots that are currently required.

指定者:

registerSlots 在接口中 DeclarativeSlotPool

覆盖:

registerSlots 在类中 DefaultDeclarativeSlotPool

参数:

slots - slots to register

taskManagerLocation - taskManagerLocation is the location of the offering TaskExecutor

taskManagerGateway - taskManagerGateway is the gateway to talk to the offering TaskExecutor

currentTime - currentTime is the time the slots are being offered

返回:

the successfully registered slots; the other slot offers are implicitly rejected

freeReservedSlot

public ResourceCounter freeReservedSlot(AllocationID allocationId,
                                        @Nullable
                                        Throwable cause,
                                        long currentTime)

从接口复制的说明: DeclarativeSlotPool

Frees the reserved slot identified by the given allocationId. If no slot with allocationId exists, then the call is ignored.

Whether the freed slot is returned to the owning TaskExecutor is implementation dependent.

指定者:

freeReservedSlot 在接口中 DeclarativeSlotPool

覆盖:

freeReservedSlot 在类中 DefaultDeclarativeSlotPool

参数:

allocationId - allocationId identifying the slot to release

cause - cause for releasing the slot; can be null

currentTime - currentTime when the slot was released

返回:

the resource requirements that the slot was fulfilling
