Max Gekk reassigned SPARK-44071:
--------------------------------
Assignee: Ryan Johnson
> Define UnresolvedNode trait to reduce redundancy
> ------------------------------------------------
>
> Key: SPARK-44071
> URL: https://issues.apache.org/jira/browse/SPARK-44071
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 3.5.0
> Reporter: Ryan Johnson
> Assignee: Ryan Johnson
> Priority: Major
>
> Looking at
> [unresolved.scala|https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/unresolved.scala],
> spark would benefit from an {{UnresolvedNode}} trait that various
> {{UnresolvedFoo}} classes could inherit from:
> {code:java}
> trait UnresolvedNode extends LogicalPlan {
> override def output: Seq[Attribute] = Nil
> override lazy val resolved = false
> }{code}
> Today, the code is duplicated in ~20 locations.
