Sahil Takiar commented on HIVE-18525:
-------------------------------------
Thanks for the feedback [~xuefuz]!
{quote} s a related question, do we show the plan at the job level? That is,
show the whole query plan for a spark job. That could be useful too. {quote}
That would be useful too. I haven't found a way to do that in the Spark Web UI
yet. This might be possible if we implement HIVE-18515, but that would require
quite a bit of work.
Attached an updated patch + RB link; new patch includes a unit test, PerLogger
integration, and some other cleanup.

> More of an investigation JIRA. The Spark UI has a "long description" of each
> stage in the Spark DAG. Typically one stage in the Spark DAG corresponds to
> either a {{MapWork}} or {{ReduceWork}} object. It would be useful if the long
> description contained the explain plan of the corresponding work object.
> I'm not sure how much additional overhead this would introduce. If not the
> full explain plan, then maybe a modified one that just lists out all the
> operator tree along with each operator name.
