Constructor Detail

TaskInfo

public TaskInfo(long taskId,
                int index,
                int attemptNumber,
                long launchTime,
                String executorId,
                String host,
                scala.Enumeration.Value taskLocality,
                boolean speculative)

Method Detail

accumulables

public scala.collection.Seq<AccumulableInfo> accumulables()

Intermediate updates to accumulables during this task. Note that it is valid for the same accumulable to be updated multiple times in a single task or for two accumulables with the same name but different IDs to exist in a task.

Returns:

(undocumented)

attemptNumber

public int attemptNumber()

duration

public long duration()

executorId

public String executorId()

failed

public boolean failed()

finishTime

public long finishTime()

The time when the task has completed successfully (including the time to remotely fetch results, if necessary).

Returns:

(undocumented)

finished

public boolean finished()

gettingResult

public boolean gettingResult()

gettingResultTime

public long gettingResultTime()

The time when the task started remotely getting the result. Will not be set if the task result was sent immediately when the task finished (as opposed to sending an IndirectTaskResult and later fetching the result from the block manager).

Returns:

(undocumented)

host

public String host()

id

public String id()

index

public int index()

The index of this task within its task set. Not necessarily the same as the ID of the RDD partition that the task is computing.

Returns:

(undocumented)

killed

public boolean killed()

launchTime

public long launchTime()

running

public boolean running()

speculative

public boolean speculative()

status

public String status()

successful

public boolean successful()

taskId

public long taskId()

taskLocality

public scala.Enumeration.Value taskLocality()
