--------------------------------------
Let's discuss this in the mailing list instead of filing an issue. Looks like
it's vague about what action should be taken and more appropriate as a
discussion.
> Sparksql authentication

> Key: SPARK-32912
> URL: https://issues.apache.org/jira/browse/SPARK-32912
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: fengchunfeng
> Priority: Major
>
> At present, we want to implement the same authentication module as hive,
> mainly to realize the blood relationship between table and column (field
> name). According to the survey, spark is used to resolve the corresponding
> relationship based on antrl4. However, the test shows that it does not
> support multi-layer nested query well, and can not accurately locate the
> corresponding relationship between table and column. We hope that the
> predecessors can provide help and relative Should the reference material, I
> will be very grateful, thank you
