方法详细资料

getNumberOfRestarts

protected long getNumberOfRestarts()

指定者:

getNumberOfRestarts 在类中 SchedulerBase

startSchedulingInternal

protected void startSchedulingInternal()

指定者:

startSchedulingInternal 在类中 SchedulerBase

updateTaskExecutionStateInternal

protected void updateTaskExecutionStateInternal(ExecutionVertexID executionVertexId,
                                                TaskExecutionState taskExecutionState)

覆盖:

updateTaskExecutionStateInternal 在类中 SchedulerBase

handleGlobalFailure

public void handleGlobalFailure(Throwable error)

指定者:

handleGlobalFailure 在接口中 SchedulerNG

scheduleOrUpdateConsumersInternal

protected void scheduleOrUpdateConsumersInternal(ExecutionVertexID producerVertexId,
                                                 ResultPartitionID partitionId)

覆盖:

scheduleOrUpdateConsumersInternal 在类中 SchedulerBase

allocateSlotsAndDeploy

public void allocateSlotsAndDeploy(List<ExecutionVertexDeploymentOption> executionVertexDeploymentOptions)

从接口复制的说明: SchedulerOperations

Allocate slots and deploy the vertex when slots are returned. The given order will be respected, i.e. tasks with smaller indices will be deployed earlier. Only vertices in CREATED state will be accepted. Errors will happen if scheduling Non-CREATED vertices.

指定者:

allocateSlotsAndDeploy 在接口中 SchedulerOperations

参数:

executionVertexDeploymentOptions - The deployment options of tasks to be deployed
