类 InputOutputFormatVertex

java.lang.Object

org.apache.flink.runtime.jobgraph.JobVertex

org.apache.flink.runtime.jobgraph.InputOutputFormatVertex

所有已实现的接口:

Serializable

public class InputOutputFormatVertex
extends JobVertex

A task vertex that runs an initialization and a finalization on the master. If necessary, it tries to deserialize input and output formats, and initialize and finalize them on master.

方法详细资料

initializeOnMaster

public void initializeOnMaster(JobVertex.InitializeOnMasterContext context)
                        throws Exception

从类复制的说明: JobVertex

A hook that can be overwritten by sub classes to implement logic that is called by the master when the job starts.

覆盖:

initializeOnMaster 在类中 JobVertex

参数:

context - Provides contextual information for the initialization

抛出:

Exception - The method may throw exceptions which cause the job to fail immediately.

finalizeOnMaster

public void finalizeOnMaster(JobVertex.FinalizeOnMasterContext context)
                      throws Exception

从类复制的说明: JobVertex

getFormatDescription

public String getFormatDescription(OperatorID operatorID)

setFormatDescription

public void setFormatDescription(OperatorID operatorID,
                                 String formatDescription)
