    • Method Detail

      • getTaskId

        TaskId getTaskId()

      • getNodeId

        String getNodeId()

      • start

        void start()

      • addSplits

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

      • noMoreSplits

        void noMoreSplits​(PlanNodeId sourceId)

      • 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.
