public interface RemoteTask

  • Method Details

    • getTaskId

      TaskId getTaskId()

    • getNodeId

      String getNodeId()

    • getTaskInfo

      TaskInfo getTaskInfo()

    • getTaskStatus

      TaskStatus getTaskStatus()

    • start

      void start()

    • addSplits

      void addSplits(com.google.common.collect.Multimap<PlanNodeId,Split> splits)

    • noMoreSplits

      void noMoreSplits(PlanNodeId sourceId)

    • noMoreSplits

      void noMoreSplits(PlanNodeId sourceId, Lifespan lifespan)

    • setOutputBuffers

      void setOutputBuffers(OutputBuffers outputBuffers)

    • addStateChangeListener

      void addStateChangeListener(StateMachine.StateChangeListener<TaskStatus> stateChangeListener)
      Listener is always notified asynchronously using a dedicated notification thread pool so, care should be taken to avoid leaking this when adding a listener in a constructor. Additionally, it is possible notifications are observed out of order due to the asynchronous execution.

    • addFinalTaskInfoListener

      void addFinalTaskInfoListener(StateMachine.StateChangeListener<TaskInfo> stateChangeListener)
      Add a listener for the final task info. This notification is guaranteed to be fired only once. Listener is always notified asynchronously using a dedicated notification thread pool so, care should be taken to avoid leaking this when adding a listener in a constructor. Additionally, it is possible notifications are observed out of order due to the asynchronous execution.

    • whenSplitQueueHasSpace

    • cancel

      void cancel()

    • abort

      void abort()

    • getPartitionedSplitsInfo

      PartitionedSplitsInfo getPartitionedSplitsInfo()

    • fail

      void fail(Throwable cause)

    • getQueuedPartitionedSplitsInfo

      PartitionedSplitsInfo getQueuedPartitionedSplitsInfo()
