方法详细资料

handleRequest

protected VertexFlameGraph handleRequest(HandlerRequest<EmptyRequestBody> request,
                                         AccessExecutionJobVertex jobVertex)
                                  throws RestHandlerException

从类复制的说明: AbstractJobVertexHandler

Called for each request after the corresponding AccessExecutionJobVertex has been retrieved from the AccessExecutionGraph.

指定者:

handleRequest 在类中 AbstractJobVertexHandler<VertexFlameGraph,JobVertexFlameGraphParameters>

参数:

request - the request

jobVertex - the execution job vertex

返回:

the response

抛出:

RestHandlerException - if the handler could not process the request

close

public void close()
           throws Exception

抛出:

Exception

disabledHandler

public static AbstractRestHandler<?,?,?,?> disabledHandler(GatewayRetriever<? extends RestfulGateway> leaderRetriever,
                                                           org.apache.flink.api.common.time.Time timeout,
