类 ResourceManagerPartitionTrackerImpl

java.lang.Object

org.apache.flink.runtime.io.network.partition.ResourceManagerPartitionTrackerImpl

所有已实现的接口:

ResourceManagerPartitionTracker

public class ResourceManagerPartitionTrackerImpl
extends Object
implements ResourceManagerPartitionTracker

Default ResourceManagerPartitionTracker implementation.

Internal tracking info must only be updated upon reception of a ClusterPartitionReport, as the task executor state is the source of truth.

processTaskExecutorClusterPartitionReport

public void processTaskExecutorClusterPartitionReport(ResourceID taskExecutorId,
                                                      ClusterPartitionReport clusterPartitionReport)

从接口复制的说明: ResourceManagerPartitionTracker

Processes ClusterPartitionReport of a task executor. Updates the tracking information for the respective task executor. Any partition no longer being hosted on the task executor is considered lost, corrupting the corresponding data set. For any such data set this method issues partition release calls to all task executors that are hosting partitions of this data set.

指定者:

processTaskExecutorClusterPartitionReport 在接口中 ResourceManagerPartitionTracker

参数:

taskExecutorId - origin of the report

clusterPartitionReport - partition report

processTaskExecutorShutdown

public void processTaskExecutorShutdown(ResourceID taskExecutorId)

从接口复制的说明: ResourceManagerPartitionTracker

Processes the shutdown of task executor. Removes all tracking information for the given executor, determines datasets that may be corrupted by the shutdown (and implied loss of partitions). For any such data set this method issues partition release calls to all task executors that are hosting partitions of this data set, and issues release calls.

指定者:

processTaskExecutorShutdown 在接口中 ResourceManagerPartitionTracker

参数:

taskExecutorId - task executor that shut down

releaseClusterPartitions

public CompletableFuture<Void> releaseClusterPartitions(IntermediateDataSetID dataSetId)

从接口复制的说明: ResourceManagerPartitionTracker

Issues a release calls to all task executors that are hosting partitions of the given data set.

指定者:

releaseClusterPartitions 在接口中 ResourceManagerPartitionTracker

参数:

dataSetId - data set to release

listDataSets

public Map<IntermediateDataSetID,DataSetMetaInfo> listDataSets()

从接口复制的说明: ResourceManagerPartitionTracker

Returns all data sets for which partitions are being tracked.

指定者:

listDataSets 在接口中 ResourceManagerPartitionTracker

返回:

tracked datasets
