Apache Spark reassigned SPARK-19598:
------------------------------------
Assignee: (was: Apache Spark)
> Remove the alias parameter in UnresolvedRelation
> ------------------------------------------------
>
> Key: SPARK-19598
> URL: https://issues.apache.org/jira/browse/SPARK-19598
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Reynold Xin
>
> UnresolvedRelation has a second argument named "alias", for assigning the
> relation an alias. I think we can actually remove it and replace its use with
> a SubqueryAlias.
> This would actually simplify some analyzer code to only match on
> SubqueryAlias. For example, the broadcast hint pull request can have one
> fewer case https://github.com/apache/spark/pull/16925/files.
