handleCheckpointRequest

protected CheckpointStatistics handleCheckpointRequest(HandlerRequest<EmptyRequestBody> ignored,
                                                       AbstractCheckpointStats checkpointStats)

从类复制的说明: AbstractCheckpointHandler

Called for each request with the corresponding AbstractCheckpointStats instance.

指定者:

handleCheckpointRequest 在类中 AbstractCheckpointHandler<CheckpointStatistics,CheckpointMessageParameters>

参数:

ignored - for further information

checkpointStats - for which the handler is called

返回:

Response

archiveJsonWithPath

public Collection<ArchivedJson> archiveJsonWithPath(AccessExecutionGraph graph)
                                             throws IOException

从接口复制的说明: OnlyExecutionGraphJsonArchivist

Returns a Collection of ArchivedJsons containing JSON responses and their respective REST URL for a given job.

The collection should contain one entry for every response that could be generated for the given job, for example one entry for each task. The REST URLs should be unique and must not contain placeholders.

指定者:

archiveJsonWithPath 在接口中 OnlyExecutionGraphJsonArchivist

参数:

graph - AccessExecutionGraph for which the responses should be generated

返回:

Collection containing an ArchivedJson for every response that could be generated for the given job

抛出:

IOException - thrown if the JSON generation fails
