Method Detail

getUserClassLoader

ClassLoader getUserClassLoader()

getJobID

JobID getJobID()

getBlobWriter

BlobWriter getBlobWriter()

getJobInformationOrBlobKey

Either<SerializedValue<JobInformation>,PermanentBlobKey> getJobInformationOrBlobKey()

getPartitionLocationConstraint

TaskDeploymentDescriptorFactory.PartitionLocationConstraint getPartitionLocationConstraint()

getFutureExecutor

Executor getFutureExecutor()

Returns the ExecutionContext associated with this ExecutionGraph.

Returns:

ExecutionContext associated with this ExecutionGraph

getJobMasterMainThreadExecutor

@Nonnull
ComponentMainThreadExecutor getJobMasterMainThreadExecutor()

getShuffleMaster

ShuffleMaster<? extends ShuffleDescriptor> getShuffleMaster()

getPartitionTracker

JobMasterPartitionTracker getPartitionTracker()

registerExecution

void registerExecution(Execution exec)

deregisterExecution

void deregisterExecution(Execution exec)

getPartitionGroupReleaseStrategy

PartitionGroupReleaseStrategy getPartitionGroupReleaseStrategy()

jobVertexFinished

void jobVertexFinished()

jobVertexUnFinished

void jobVertexUnFinished()

getExecutionDeploymentListener

ExecutionDeploymentListener getExecutionDeploymentListener()

failGlobal

void failGlobal(Throwable t)

Fails the execution graph globally.

This global failure is meant to be triggered in cases where the consistency of the execution graph' state cannot be guaranteed any more (for example when catching unexpected exceptions that indicate a bug or an unexpected call race), and where a full restart is the safe way to get consistency back.

Parameters:

t - The exception that caused the failure.

notifyExecutionChange

void notifyExecutionChange(Execution execution,
                           ExecutionState previousState,
                           ExecutionState newExecutionState)

notifySchedulerNgAboutInternalTaskFailure

void notifySchedulerNgAboutInternalTaskFailure(ExecutionAttemptID attemptId,
                                               Throwable t,
                                               boolean cancelTask,
                                               boolean releasePartitions)

getEdgeManager

EdgeManager getEdgeManager()

getExecutionVertexOrThrow

ExecutionVertex getExecutionVertexOrThrow(ExecutionVertexID id)

getResultPartitionOrThrow

IntermediateResultPartition getResultPartitionOrThrow(IntermediateResultPartitionID id)

deleteBlobs

void deleteBlobs(List<PermanentBlobKey> blobKeys)

getJobVertex

ExecutionJobVertex getJobVertex(JobVertexID id)

isDynamic

boolean isDynamic()

getExecutionGraphID

ExecutionGraphID getExecutionGraphID()

getClusterPartitionShuffleDescriptors

List<ShuffleDescriptor> getClusterPartitionShuffleDescriptors(IntermediateDataSetID intermediateResultPartition)

Get the shuffle descriptors of the cluster partitions ordered by partition number.
