Method Detail

listDataSets

CompletableFuture<Map<IntermediateDataSetID,DataSetMetaInfo>> listDataSets()

Returns all datasets for which partitions are being tracked.

Returns:

tracked datasets

releaseClusterPartitions

CompletableFuture<Void> releaseClusterPartitions(IntermediateDataSetID dataSetToRelease)

Releases all partitions associated with the given dataset.

Parameters:

dataSetToRelease - dataset for which all associated partitions should be released

Returns:

future that is completed once all partitions have been released

reportClusterPartitions

CompletableFuture<Void> reportClusterPartitions(ResourceID taskExecutorId,
                                                ClusterPartitionReport clusterPartitionReport)

Report the cluster partitions status in the task executor.

Parameters:

taskExecutorId - The id of the task executor.

clusterPartitionReport - The status of the cluster partitions.

Returns:

future that is completed once the report have been processed.

getClusterPartitionsShuffleDescriptors

CompletableFuture<List<ShuffleDescriptor>> getClusterPartitionsShuffleDescriptors(IntermediateDataSetID intermediateDataSetID)
