lining updated FLINK-14738:
---------------------------
Description:
When the job is running, we can get the operator's metrics, such as [subtask
index]. [operator Name]. [metric name]
However, once finished, only the metrics for the task record can be obtained.
Is it because only the record metrics for the task are stored by
TaskIOMetricGroup.createSnapshot?
was:When the job is running, we could get operators' metrics. But when it's
finished, only get task‘s record num. If there any way could get any operator's
metrics?
> Job which status is finished, get operator metric
