CheckpointFailureManager

public CheckpointFailureManager(int tolerableCpFailureNumber,
                                CheckpointFailureManager.FailJobCallback failureCallback)

方法详细资料

handleJobLevelCheckpointException

public void handleJobLevelCheckpointException(CheckpointException exception,
                                              long checkpointId)

Handle job level checkpoint exception with a handler callback.

参数:

exception - the checkpoint exception.

checkpointId - the failed checkpoint id used to count the continuous failure number based on checkpoint id sequence. In trigger phase, we may not get the checkpoint id when the failure happens before the checkpoint id generation. In this case, it will be specified a negative latest generated checkpoint id as a special flag.

handleTaskLevelCheckpointException

public void handleTaskLevelCheckpointException(CheckpointException exception,
                                               long checkpointId,
                                               ExecutionAttemptID executionAttemptID)

Handle task level checkpoint exception with a handler callback.

参数:

exception - the checkpoint exception.

checkpointId - the failed checkpoint id used to count the continuous failure number based on checkpoint id sequence. In trigger phase, we may not get the checkpoint id when the failure happens before the checkpoint id generation. In this case, it will be specified a negative latest generated checkpoint id as a special flag.

executionAttemptID - the execution attempt id, as a safe guard.

checkFailureCounter

public void checkFailureCounter(CheckpointException exception,
                                long checkpointId)

handleCheckpointSuccess

public void handleCheckpointSuccess(long checkpointId)

Handle checkpoint success.

参数:

checkpointId - the failed checkpoint id used to count the continuous failure number based on checkpoint id sequence.
