接口 JobTable.Job

封闭接口:

JobTable

public static interface JobTable.Job

A job contains services which are bound to the lifetime of a Flink job. Moreover, it can be connected to a leading JobManager and then store further services which are bound to the lifetime of the JobManager connection.

Accessing any methods after a job has been closed will throw an IllegalStateException.

方法概要

限定符和类型	方法和说明
Optional<JobTable.Connection>	asConnection() Returns the associated JobTable.Connection if the job is connected to a JobManager.
void	close() Closes this job and removes it from the owning JobTable.
JobTable.Connection	connect(ResourceID resourceId, JobMasterGateway jobMasterGateway, TaskManagerActions taskManagerActions, CheckpointResponder checkpointResponder, GlobalAggregateManager aggregateManager, PartitionProducerStateChecker partitionStateChecker) Connects the job to a JobManager and associates the provided services with this connection.
org.apache.flink.api.common.JobID	getJobId() Returns the JobID which is associated with this job.
boolean	isConnected() Returns true if the job is connected to a JobManager.

方法详细资料

isConnected

boolean isConnected()

Returns true if the job is connected to a JobManager.

返回:

true if the job is connected to a JobManager, otherwise false

getJobId

org.apache.flink.api.common.JobID getJobId()

Returns the JobID which is associated with this job.

返回:

job id which is associated with this job

asConnection

Optional<JobTable.Connection> asConnection()

Returns the associated JobTable.Connection if the job is connected to a JobManager.

返回:

an Optional containing the associated JobTable.Connection instance if the job is connected to a leading JobManager, or an empty Optional if the job is not connected

connect

JobTable.Connection connect(ResourceID resourceId,
                            JobMasterGateway jobMasterGateway,
                            TaskManagerActions taskManagerActions,
                            CheckpointResponder checkpointResponder,
                            GlobalAggregateManager aggregateManager,
                            PartitionProducerStateChecker partitionStateChecker)

Connects the job to a JobManager and associates the provided services with this connection.

A job can only be connected iff Job#isConnected() == false.

参数:

resourceId - resourceId of the JobManager to connect to

jobMasterGateway - jobMasterGateway of the JobManager to connect to

taskManagerActions - taskManagerActions associated with this connection

checkpointResponder - checkpointResponder associated with this connection

aggregateManager - aggregateManager associated with this connection

partitionStateChecker - partitionStateChecker associated with this connection

返回:

the established JobTable.Connection

抛出:

IllegalStateException - if the job is already connected

close

void close()

Closes this job and removes it from the owning JobTable.
