K SQL to capitalize those 'tokens'
before invoking the parser?
If so, why not just modify the SqlBase.g4 to accept lower cases keywords?
Thanks

Could be a tangential idea but might help: Why not use queryExecution and
logicalPlan objects that are available when you execute a query using
SparkSession and get a DataFrame back? The Json representation contains
almost all the info that you need and you don't need to go to Hive to get
this info
Explain extended or explain would list the plan along with the tables. Not
aware of any statements that explicitly list dependencies or tables
directly.
