Package org.apache.flink.runtime.executiongraph

Interface InternalExecutionGraphAccessor

All Known Implementing Classes:
DefaultExecutionGraph
public interface InternalExecutionGraphAccessor
This interface encapsulates all methods needed by ExecutionJobVertex / ExecutionVertices / Execution from the DefaultExecutionGraph.

  • Method Details

    • getUserClassLoader

      ClassLoader getUserClassLoader()

    • getJobID

      org.apache.flink.api.common.JobID getJobID()

    • getBlobWriter

      BlobWriter getBlobWriter()

    • getFutureExecutor

      Executor getFutureExecutor()
      Returns the ExecutionContext associated with this ExecutionGraph.
      Returns:
      ExecutionContext associated with this ExecutionGraph

    • getJobMasterMainThreadExecutor

      @Nonnull org.apache.flink.runtime.concurrent.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.

    • getMarkPartitionFinishedStrategy

      MarkPartitionFinishedStrategy getMarkPartitionFinishedStrategy()

    • getJobVertexInputInfo

      JobVertexInputInfo getJobVertexInputInfo(JobVertexID jobVertexId, IntermediateDataSetID resultId)
      Get the input info of a certain input of a certain job vertex.
      Parameters:
      jobVertexId - the job vertex id
      resultId - the input(intermediate result) id
      Returns:
      the input info
