-----------------------------------
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).
