JobAccumulatorsHandler

public JobAccumulatorsHandler(GatewayRetriever<? extends RestfulGateway> leaderRetriever,
                              org.apache.flink.api.common.time.Time timeout,
                              Map<String,String> responseHeaders,

                              Executor executor)

方法详细资料

handleRequest

protected JobAccumulatorsInfo handleRequest(HandlerRequest<EmptyRequestBody> request,
                                            AccessExecutionGraph graph)
                                     throws RestHandlerException

指定者:

handleRequest 在类中 AbstractAccessExecutionGraphHandler<JobAccumulatorsInfo,JobAccumulatorsMessageParameters>

抛出:

RestHandlerException

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
