Aihua Xu commented on HIVE-18690:
---------------------------------
[~stakiar] The patch looks great. Can you check the style errors above? Also,
one more question: would "file not visible" the only cause for the exception in
updateSparkBytesWrittenMetrics? If not, maybe we can change the message to
{{log.debug("Unable to collect file stats for file:" + path + ". Output
metrics may be inaccurate", e);}}
> Integrate with Spark OutputMetrics

> Spark has an {{OutputMetrics}} it uses to expose records / bytes written. We
> currently don't integrate with it and the Spark UI shows a blank value for
> output records / bytes. We have our own customer accumulators instead (like
> {{HIVE_RECORDS_OUT}}).
> Spark exposes the {{OutputMetrics}} object inside individual tasks via the
> {{TaskContext.get()}} method. We can use this method to access the
> {{OutputMetrics}} object and update it.
