所有已实现的接口:

Serializable

public class MutableIOMetrics
extends IOMetrics

This class is a mutable version of the IOMetrics class that allows adding up IO-related metrics.

For finished jobs these metrics are stored in the ExecutionGraph as another IOMetrics. For running jobs these metrics are retrieved using the MetricFetcher.

This class provides a common interface to handle both cases, reducing complexity in various handlers (like the JobVertexDetailsHandler).

addIOMetrics

public void addIOMetrics(AccessExecution attempt,
                         @Nullable
                         MetricFetcher fetcher,
                         String jobID,
                         String taskID)

Adds the IO metrics for the given attempt to this object. If the AccessExecution is in a terminal state the contained IOMetrics object is added. Otherwise the given MetricFetcher is used to retrieve the required metrics.

参数:

attempt - Attempt whose IO metrics should be added

fetcher - MetricFetcher to retrieve metrics for running jobs

jobID - JobID to which the attempt belongs

taskID - TaskID to which the attempt belongs
