-----------------------------------
Summary: Add explain plan to Hive on Spark Web UI
Key: HIVE-18525
URL: https://issues.apache.org/jira/browse/HIVE-18525
Project: Hive
Issue Type: Sub-task
Components: Spark
Reporter: Sahil Takiar
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.
