> For queries which scan multiple tables, it will be convenient if the DAG shown in Spark UI also showed which table is being scanned. This will make debugging easier. For this JIRA, I am scoping those for hive table scans only. For Spark native tables, the table scan node is abstracted out as a `WholeStageCodegen` node (which might be doing more things besides table scan).
