[jira] [Created] (SPARK-23034) Display tablename for `HiveTableScan` node in UI

Tejas Patil created SPARK-23034:
-----------------------------------

             Summary: Display tablename for `HiveTableScan` node in UI
                 Key: SPARK-23034
                 URL: https://issues.apache.org/jira/browse/SPARK-23034
             Project: Spark
          Issue Type: Improvement
          Components: SQL, Web UI
    Affects Versions: 2.2.1
            Reporter: Tejas Patil
            Priority: Trivial


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).
