@gatorsmile, I'm able to access `groupingExprs` from `SQLUtils.scala`
through `val groupingExprs: Seq[Expression],` however it seems to be
challenging to access the name of the column from pure expression. In
RelationalGroupedDataset it is using alias to create a named expression:
https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/RelationalGroupedDataset.scala#L83
What would you suggest as a best option of accessing column name from
`Expression` ?
Thank you,
Narine
