Class TransferableJobProcessInformation

java.lang.Object

com.hazelcast.mapreduce.impl.task.TransferableJobProcessInformation

All Implemented Interfaces:

JobProcessInformation, Portable

public class TransferableJobProcessInformation
extends Object
implements JobProcessInformation, Portable

This implementation of JobProcessInformation is used to transmit the currently processed number of records and the partition states to a requesting client. This information can only be requested by the job emitting client and by requesting it at the job owner.

Method Summary

Modifier and Type	Method and Description
int	getClassId()
int	getFactoryId()
JobPartitionState[]	getPartitionStates() Returns an array of JobPartitionStates holding information about the processing state (JobPartitionState.State) and the processing owner of this partition. The index of the JobPartitionState inside of the array is the number of the processed partition if the KeyValueSource is PartitionIdAware or a randomly assigned id for the different members of the cluster.
int	getProcessedRecords() Returns the number of processed records. The number of processed records is not a real time value but updated on regular base (after 1000 processed elements per node).

Method Detail

getPartitionStates

public JobPartitionState[] getPartitionStates()

Description copied from interface: JobProcessInformation

Returns an array of JobPartitionStates holding information about the processing state (JobPartitionState.State) and the processing owner of this partition.
The index of the JobPartitionState inside of the array is the number of the processed partition if the KeyValueSource is PartitionIdAware or a randomly assigned id for the different members of the cluster.

Specified by:

getPartitionStates in interface JobProcessInformation

Returns:

partition state array with actual state information

getProcessedRecords

public int getProcessedRecords()

Description copied from interface: JobProcessInformation
