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

taskId

public long taskId()

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)

attemptNumber

public int attemptNumber()

launchTime

public long launchTime()

executorId

public String executorId()

host

public String host()

taskLocality

public scala.Enumeration.Value taskLocality()

speculative

public boolean speculative()

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)

accumulables

public scala.collection.mutable.ListBuffer<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)

finishTime

public long finishTime()

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

Returns:

(undocumented)

failed

public boolean failed()

killed

public boolean killed()

gettingResult

public boolean gettingResult()

finished

public boolean finished()

successful

public boolean successful()

running

public boolean running()

status

public String status()

id

public String id()

duration

public long duration()
