Method Detail

getTaskId

TaskId getTaskId()

getNodeId

String getNodeId()

getTaskInfo

TaskInfo getTaskInfo()

getTaskStatus

TaskStatus getTaskStatus()

getRemoteTaskLocation

URI getRemoteTaskLocation()

TODO: this should be merged into getTaskStatus once full thrift support is in-place for v1/task

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)

removeRemoteSource

com.google.common.util.concurrent.ListenableFuture<?> removeRemoteSource(TaskId remoteSourceTaskId)

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

com.google.common.util.concurrent.ListenableFuture<?> whenSplitQueueHasSpace(long weightThreshold)

cancel

void cancel()

abort

void abort()

getPartitionedSplitsInfo

PartitionedSplitsInfo getPartitionedSplitsInfo()

getQueuedPartitionedSplitsInfo

PartitionedSplitsInfo getQueuedPartitionedSplitsInfo()

getUnacknowledgedPartitionedSplitCount

int getUnacknowledgedPartitionedSplitCount()
