类 CheckpointResourcesCleanupRunner

java.lang.Object

org.apache.flink.runtime.dispatcher.cleanup.CheckpointResourcesCleanupRunner

所有已实现的接口:

AutoCloseable, JobManagerRunner, org.apache.flink.util.AutoCloseableAsync

public class CheckpointResourcesCleanupRunner
extends Object
implements JobManagerRunner

CheckpointResourcesCleanupRunner implements JobManagerRunner in a way, that only the checkpoint-related resources are instantiated. It triggers any job-specific cleanup that's usually performed by the JobMaster without rebuilding the corresponding ExecutionGraph.

方法详细资料

closeAsync

public CompletableFuture<Void> closeAsync()

指定者:

closeAsync 在接口中 org.apache.flink.util.AutoCloseableAsync

start

public void start()
           throws Exception

从接口复制的说明: JobManagerRunner

Start the execution of the JobMaster.

指定者:

start 在接口中 JobManagerRunner

抛出:

Exception - if the JobMaster cannot be started

getJobMasterGateway

public CompletableFuture<JobMasterGateway> getJobMasterGateway()

从接口复制的说明: JobManagerRunner

Get the JobMasterGateway of the JobMaster. The future is only completed if the JobMaster becomes leader.

指定者:

getJobMasterGateway 在接口中 JobManagerRunner

返回:

Future with the JobMasterGateway once the underlying JobMaster becomes leader

getResultFuture

public CompletableFuture<JobManagerRunnerResult> getResultFuture()

从接口复制的说明: JobManagerRunner

Get the result future of this runner. The future is completed once the executed job reaches a globally terminal state or if the initialization of the JobMaster fails. If the result future is completed exceptionally via JobNotFinishedException, then this signals that the job has not been completed successfully. All other exceptional completions denote an unexpected exception which leads to a process restart.

指定者:

getResultFuture 在接口中 JobManagerRunner

返回:

Future which is completed with the job result

getJobID

public org.apache.flink.api.common.JobID getJobID()

从接口复制的说明: JobManagerRunner

Get the job id of the executed job.

指定者:

getJobID 在接口中 JobManagerRunner

返回:

job id of the executed job

cancel

public CompletableFuture<Acknowledge> cancel(org.apache.flink.api.common.time.Time timeout)

从接口复制的说明: JobManagerRunner

Cancels the currently executed job.

指定者:

cancel 在接口中 JobManagerRunner

参数:

timeout - of this operation

返回:

Future acknowledge of the operation

requestJobStatus

public CompletableFuture<org.apache.flink.api.common.JobStatus> requestJobStatus(org.apache.flink.api.common.time.Time timeout)

从接口复制的说明: JobManagerRunner

Requests the current job status.

指定者:

requestJobStatus 在接口中 JobManagerRunner

参数:

timeout - for the rpc call

返回:

Future containing the current job status

requestJobDetails

public CompletableFuture<JobDetails> requestJobDetails(org.apache.flink.api.common.time.Time timeout)

从接口复制的说明: JobManagerRunner

Request the details of the executed job.

指定者:

requestJobDetails 在接口中 JobManagerRunner

参数:

timeout - for the rpc call

返回:

Future details of the executed job

requestJob

public CompletableFuture<ExecutionGraphInfo> requestJob(org.apache.flink.api.common.time.Time timeout)

从接口复制的说明: JobManagerRunner

Requests the ExecutionGraphInfo of the executed job.

指定者:

requestJob 在接口中 JobManagerRunner

参数:

timeout - for the rpc call

返回:

Future which is completed with the ExecutionGraphInfo of the executed job

isInitialized

public boolean isInitialized()

从接口复制的说明: JobManagerRunner

Flag indicating if the JobManagerRunner has been initialized.

指定者:

isInitialized 在接口中 JobManagerRunner

返回:

true if the JobManagerRunner has been initialized.
