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<MetricCollectionResponseBody,JobVertexMessageParameters>

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
